Abstract (sommario):

Indonesian Natural Sand, Zircon, is an Indonesia’s natural resource that contains zirconia, silica, titania and alumina. In Dentistry, zirconia as one of the content in natural zircon sand, have the potential to be the material for filler composites. The purpose of this research was to analyze the Zirconia-Calcium-Silicate Particle (ZrO2CaO-SiO2) synthesized from Indonesia natural sand, zircon, in microstructural way. Methods: By synthesizing ZirconiaCalcium-Silicate particle (ZrO2-CaO-SiO2) from Indonesia natural zircon sand, using spray pyrolysis method. A precursor solution that is used consists of zirconil nitrate (Zr (NO3) 2), sodium silicate (Na2SiO3), and calcium hydroxide (Ca (OH) 2). Variations in the temperature of the reactor that are used were 4000C, 4500C, and 5000C with a feed rate of 6 L / min and a piezoelectric frequency of 1.7 MHz. Result showed that the better content in zirconia-calcium-silicate is the one that was synthesized at a temperature of 4500C, based on the results of EDS, SEM and XRD. The composition that is obtained in the zirconia-calcium-silicate particle has a ratio of 1: 14: 4 with the size of 500-1000nm, and has a tetragonal crystal zirconium silicate structure and dicalcium monoclinic silicate. From this research it can be concluded that the result that was synthesized at a temperature of 4500C is adequate to use as a filler based on the characterization result of SEM and XRD.

Abstract (sommario):

ABSTRAKKeberadaan zirkon (ZrSiO4) di alam kebanyakan berasosiasi dengan beberapa senyawa oksida berharga (SOB) seperti TiO2 dan oksida logam tanah jarang atau rare earth oxides (REO). Keterdapatan mineral alam di Indonesia yang mengandung zirkonium (Zr) dan REO tersebar di 13 wilayah mulai dari Provinsi Aceh sampai Papua Barat. Berdasarkan hal tersebut, maka tujuan penelitian adalah melakukan kajian integrasi teknologi pengolahan pasir zirkon lokal yang mengandung TiO2 dan REO. Penelitian dilakukan dengan menganalisis kandungan SOB dalam sampel pasir zirkon dari daerah Landak dan Tumbang Titi Kalimantan Barat serta Bangka menggunakan XRF. Berdasarkan kandungan SOB dalam pasir zirkon tersebut dapat diprediksi bahwa pasir zirkon dari daerah Landak dan Tumbang Titi Kalimantan Barat serta Bangka mengandung mineral zirkon (ZrSiO4), ilmenit (FeTiO3), monasit (LREE, Th)PO4, dan senotim (HREE, Y, Th)PO4. Berbasis jenis mineral tersebut diperoleh hasil kajian berupa diagram alir proses konsep teknologi konsentrat zirkon menjadi ZrO2 (zirkonia) dan ZrOCl2.8H2O (zirkonium oksiklorida) derajat industri serta zirkonia dan zirconium chemicals derajat nuklir, ilmenit menjadi TiO2, monasit menjadi Nd2O3 dan konsentrat Th(OH)4, senotim menjadi Y2O3, Gd2O3 dan konsentrat Th(OH)4 dalam satu kawasan pilot plant atau pabrik yang terintegrasi. Hasil kajian disimpulkan bahwa konsep pengolahan pasir zirkon lokal yang mengandung monasit, senotim, dan ilmenit dapat dilakukan secara terintegrasi dalam satu kawasan pabrik dengan hasil multi produk. Jika hal tersebut dapat direalisasikan di Indonesia dengan tambahan sistem pengolahan air limbah terpadu, maka selain aman bagi lingkungan juga dapat menghemat biaya produksi dan memberikan nilai tambah ekonomi bagi para pemegang izin usaha pertambangan zirkon. ABSTRACTThe existence of zircon (ZrSiO4) in the nature is mostly associated with some of the valuable oxide compounds (VOC), such as TiO2 and rare earth oxides (REO). The existence of natural minerals in Indonesia containing zirconium (Zr) and REO lies in 13 regions, ranging from Aceh to West Papua province. Based on those aforementioned aspects, the goal of this research is to conduct the study of integrated technology of local zircon sand processing containing TiO2 and REO. The study was conducted by analyzing the content of VOC in zircon sand samples from the areas of Landak and Tumbang Titi West Kalimantan and Bangka by using XRF. Based on the content of VOC in this zircon sand, it can be predicted that the zircon sand from the area of Landak and Tumbang Titi West Kalimantan and Bangka contains mineral zircon (ZrSiO4), ilmenite (FeTiO3), monazite (LREE, Th)PO4, and xenotime (HREE, Th)PO4. Based on these types of mineral, the flow chart of beneficiation technology process to increase the concentration of each mineral and the flow chart of zircon concentrate process into ZrO2(zirconia) and ZrOCl2.8H2O (zirconium oxychloride) industrial grade and zirconia and zirconium chemicals nuclear grade, ilmenite into TiO2, monazite into Nd2O3, and Th(OH)4 concentrate, xenotime into Y2O3, Gd2O3, and Th(OH)4 concentrate are obtained in one area of pilot plant or an integrated factory. The results of the study concluded that the concept of local processing of zircon sands containing monazite, xenotime, and ilmenite can be either integrated in the region with the results of multi-product plant. If it can be realized in Indonesia with the addition of an integrated waste water treatment system, then in addition to safe for the environment can also save on production costs and give economic added value for shareholders zircon mining permit

Abstract (sommario):

Trachyte in Zoumaying was erupted in Eocene by 40Ar-39Ar age-dating in previous studies. Multielement Geochemistry analysis and U-Pd radiochronology were introduced on zircons from trachyte in Zoumaying in this paper. The SiO2 and K2O+Na2O contents of trachytes vary between 58.59% to 68.99%, and 10% to 11%. About twenty zircons were selected from trachyte sample with fractures and zonal structure, and most of them were inheritable magmatic zircons. The result of radiochronology on zircon is 60Ma which is similar with the former result as 53.2±0.2Ma.

Research subject. U-Pb zircon dating, as well as a petrological and geochemical study of pyroxene-amphibole-, pyroxeneamphibole- biotite- and biotite-bearing fenites from the Central Alkaline Band Ilmeno-Vishnevogorsky Complex.Methods. The age of zircons was determined by an ion mass spectrometer (SHRIMP II, Centre of Isotopic Research VSEGEI). The content of REE and trace elements was estimated by secondary ion mass spectrometer methods (CAMECA IMS-4F, Valiev Institute of Physics and Technology RAS).Results. The mineralogical and geochemical (U, Th, REE) features of zircons, as well as fenites, reflect their polygenic-polychronous nature. Most zircon crystals have a metastable matrix and are characterized by averaged REE contents between igneous and hydrothermal types. These crystals are distinguished from magmatic zircons by high LREE contents and low values of Ce anomalies, and from hydrothermal zircons – by differentiated REE distribution spectra. Three ages of zircon were established: 2066–1686 (PR1), 425–404 (S2) and 284–266 (P1) Ma. PR1 zircons reflect the primary features and the degree of changes in the fenite substrate. S2 zircons, limited only to the biotite- bearing fenite, correspond to the age of the miaskite formation process. The P1 zircons clearly reflect the metasomatic process of fenitization initiated by late shear deformations. The temperature of the phenitization processes (based on the Ti content in zircons) was estimated at 630–670°C for S2 and ≤ 600°C for P1 fenites, respectively.Conclusions. Central Alkaline Band fenites were formed by the metasomatic process of PR1 substrate fenitization in the late stage (P1) of shear strains, which are widely expressed in the Ilmeno-Vishnevogorsky Complex.

Abstract (sommario):

The Chungju rare-earth element (REE) deposit is located in the central part of the Okcheon Metamorphic Belt (OMB) in the Southern Korean Peninsula and research on REE mineralization in the Gyemyeongsan Formation has been continuous since the first report in 1989. The genesis of the REE mineralization that occurred in the Gyemyeongsan Formation has been reported by previous researchers; theories include the fractional crystallization of alkali magma, magmatic hydrothermal alteration, and recurrent mineralization during metamorphism. In the Gyemyeongsan Formation, we discovered an allanite-rich vein that displays the paragenetic relationship of quartz, allanite, and zircon, and we investigated the chemistry and chronology of zircon obtained from this vein. We analyzed the zircon’s chemistry with an electron probe X-ray micro analyzer (EPMA) and laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS). The grain size of the zircon is as large as 50 µm and has an inherited core (up to 15 µm) and micrometer-sized sector zoning (up to several micrometers in size). In a previous study, the zircon ages were not obtained because the grain size was too small to analyze. In this study, we analyzed the zircon with laser ablation multi-collector inductively coupled plasma mass spectrometry (LA-MC-ICP-MS) for dating purposes. The REE patterns and occurrence of zircon in the quartz–allanite vein match well with previous reported recrystallized zircon, while the behavior of the trace elements shows differences with magmatic and hydrothermal zircon. The 206Pb/238U ages obtained from the zircon in the quartz–allanite vein are from 240.1 ± 2.9 to 257.1 ± 3.5 Ma and this age is included in the tectonic evolution period of the study area. Therefore, we suggest that the quartz–allanite veins in the Gyemyeongsan Formation were formed during the late Permian to early Triassic metamorphic period and the zircon was recrystallized at that time. The Triassic age is the first reported age with zircon dating in the Gyemyeongsan Formation and will be an important data-point for the study of the tectonic evolution of the OMB.

Abstract (sommario):

The polygenic and polychronous character of zircon texture is the key source of information on the conditions of its growth and secondary alterations. In this research the JPD method of processing of the BSE and CL images including plotting of JPD histograms and JPD maps of grains was developed and applied for quantitative study of the internal texture of zircon grains with micron spatial resolution and for its use in geochronometry. The nomenclature for distinguished zones on the generalized diagram (BSE vs. CL) is suggested for zircons of a wide range of the conditions of its formation, age, size, texture types, and degrees of structure disordering. The JPD-analysis of zircon internal texture is applied for interpretation of the nature of variations in the BSE and CL intensities within an individual heterogeneous grain (on the quantitative level) and between different grains (on the qualitative level). The approach is suggested as the preliminary stage during geochronological studies increasing the reliability of the local electron microprobe and mass spectrometry isotope dating of the mineral.

Abstract (sommario):

Based on research of the petrology, geochemistry, and zircon U–Pb dating of detrital rocks in the Late Triassic Wenbinshan Formation in southwestern Fujian, and comparing the detrital zircon ages of Wenbinshan Formation with those of Late Paleozoic – Early Mesozoic main basins in South China, the sedimentary provenance of the Late Triassic in southwestern Fujian and its implications for changes in basin properties are discussed. The research results demonstrate that there is a major age peak at 222 Ma, two subordinate age peaks at 275 Ma and 1851 Ma, and two minor age peaks at 413 Ma and 2447 Ma in the detrital zircon age spectra of the upper samples (YGP–6) of the Wenbinshan Formation, whereas there are two major age peaks at 229 Ma and 1817 Ma and other minor age peaks 265 Ma 309 Ma, 415 Ma, 1968 Ma, and 2435 Ma in the detrital zircon age spectra of the lower samples (YGP–26) of the Wenbinshan Formation. The upper samples contain fewer old detrital zircons than the lower samples, but the upper and lower samples of Wenbinshan Formation are similar in major age composition, which indicates the main provenances of the upper and lower sediments are very similar. The source rocks are mainly sedimentary rocks and their provenances are derived from a source area of recycled orogenic belt and volcanic arc orogenic belt (acidic island arc). The detrital zircon composition of the Wenbinshan Formation is mainly composed of Paleoproterozoic zircon and Late Paleozoic – Early Mesozoic zircon. In the Paleoproterozoic, sedimentary provenances were mainly derived from the Wuyi Massif and partly from northwestern Fujian-southwestern Zhejiang. As for the period of Late Paleozoic – Early Mesozoic, the provenances of the Wenbinshan Formation were derived from magmatic active belts of the Early Indosinian Epoch of northern South China, eastern South China, and the Indosinian Period of northern South China and coastal areas of eastern South China. The similarities and differences between detrital zircon age peaks of the Wenbinshan Formation in southwestern Fujian and that of the main basins in South China during the period of Late Paleozoic – Early Mesozoic indicate that from eastern coastal areas of South China to the north and interior of South China, the age composition of basin sediments has changed from simple to relatively complex, and from young sediments to older sediments. There are similarities and differences in the detrital zircon compositions of the different basins, which can indicate differences in the nature of the basins.

Abstract (sommario):

This study uses detrital zircon U-Pb geochronology to investigate the provenance of the Jurassic Sundance Formation in the western Powder River Basin, Wyoming. Understanding the provenance of the Sundance Formation is critical as it was deposited during the transition from cratonic to synorogenic sedimentation derived from the Sevier-Laramide foreland. The Sundance in the western Powder River Basin consists of an oolitic limestone and green glauconitic sandstone at the base, green shales in the middle, and a yellow quartz arenite with coquina “oyster” beds at the top. U-Pb analyses of detrital zircons using LA-ICP-MS were conducted on two samples collected in the Bud Love Wildlife Habitat Management Area, 20 km northwest of Buffalo, WY. The two samples were taken from the upper and lower sandstone members of the Sundance Formation (n=289 concordant U-Pb zircon ages). The samples show a distinct difference in detrital zircon age spectra. The lower sandstone age spectrum ranges from 260-3172 Ma with 23% of the ages being Paleozoic, 71% being Proterozoic, and 6% being Archean. This lower stratum has detrital zircon age peaks at 343, 432, 686, 1039, 1431, 1662, 1748, 1941, 2433, and 3179 Ma. The lower sandstone shows an easterly Appalachian-Ouachita provenance, which persisted in the region beginning in the Carboniferous. In comparison to the upper strata, ages range from 157-2949 Ma and age peaks at 170, 243, 440, 545, 1082, 1467, 1681, and 1985 Ma. The maximum deposition age for the upper member is 160 Ma. Mesozoic aged grains make up 15.6% of the zircons, 14.7% were Paleozoic, 65.7% were Proterozoic, and 4% were Archean in age. The appearance of Mesozoic zircons in the upper sandstone marks the first significant appearance of westerly sourced zircons, and perhaps reflects the earliest uplift of the Sevier fold and thrust belt. Previous research has found this same signature in the Sundance but not in the underlying Triassic Chugwater Formation, resulting in a broad boundary of the change in sediment dispersal and the onset of the Sevier Orogeny between the Triassic and Jurassic. This study was conducted for a higher resolution to the provenance of the Sundance Formation and to further narrow the boundary of differing sedimentation from an eastern recycled to western synorogenic source.

Abstract (sommario):

The widely use of dental composite triggers a lot of research to synthesize composite made from natural sources. One of the natural sources that could be used as a filler of composite is natural zircon sand from Indonesia. The physical properties of dental composite, such as Diametral Tensile Strength (DTS) and hardness could be affected by the filler of the composite. The aim of this research is to determine the value of diametral tensile strength and hardness of prototype composite with natural zircon sand-based filler by using geopolymerization method with various coupling agents. The procedures began from synthesizing Zirconia-Alumina-Silica filler from natural zircon sand using geopolymerization method with two different coupling agents, 3-mercapto propyltrimethoxysilane (3-MPTS) and 3-aminopropyltriethoxysilane (3-APTS), which then mixed with resin matrix to form composite resin, some of the samples were then subjected to a DTS test using Lloyd Universal Testing Machine (5.6 N initial load) until a crack/fracture was formed while some of them was subjected to a hardness test using Vickers Hardness Tester. The results showed the average DTS of dental composite using MPTS coupling agent was 13.78 MPa, while the average DTS of dental composite using APTS coupling agent was 8.90 MPa, and the average hardness result of dental composite coated by 3-MPTS was higher (20.68 VHN) than composite coated by 3-APTS (18.02 VHN). This difference could be affected by filler particle composition, filler surface area and also coupling agent variation. In conclusion, the tensile strength of the prototype resin composite sample group with the natural zircon sand filler using MPTS coupling agent was higher than the APTS coupling agent group.

Abstract (sommario):

The spatial distribution of heavy minerals along the mine paths 2014 and 2015 at the wet concentrate plant B shows an increase of heavy minerals sand concentration northwards and slime contents southwards, and it is commonly associated with depth and grain sorting; the increase of heavy minerals concentration with depth is considered to be from the surface formed by Unit 6 to the bottom of Unit 7. The Unit 82 is characterized by low heavy minerals concentrations and high slime contents declining northwards. The mineral proportion estimation suggests that ilmenite is the most abundant heavy mineral in the entire area followed by zircon, rutile and mozanite, and some accessory minerals such as chromite, kyanite, staurolite, tourmaline, epidote, spinel and quartz. The ilmenite occurrence is divided into ilmenite low (< 53% TiO₂) and high (> 53% TiO₂); the ilmenite high with zircon and rutile shows tendency to increase northwards while ilmenite low increase southwards. Zircon, monazite, rutile, chromite, kyanite and staurolite show low variability, which is probably associated with high resistance of minerals for abrasion during transportation and diagenesis. The depositional model of the Namalope deposit, in the flat area and wet concentrate plant B in particular, suggests deposition in a shallow marine environment associated with regression for deposition of Unit 6, 7 and 9 and transgression during deposition of Unit 82. The spatial distribution of heavy minerals in the Namalope deposit and its environment of deposition are the key points for discovery of new deposits around the Namalope with the same characteristic of mineral assemblage and they are used for mine strategic plans such as update block model and mine design.

Abstract (sommario):

Introduction : Depuis les premiers implants dentaires Bränemark, les techniques chirurgicales et les matériaux implantaires ont évolué. La référence en terme de matériau implantaire est le Titane. Cependant, d’autres matériaux comme le Zircone ont été proposés pour suppléer le Titane en cas d’allergie au Titane mais aussi pour améliorer la bio-intégration de l’implant dentaire et l’esthétique. Les facteurs de risques d’échec implantaire des implants en Titane incluent, entre autre, l’hygiène orale, la consommation de tabac et la mise en charge immédiate. Objectif : L’étude ZIR-ROC a donc été menée dans le but d’étudier le taux de survie de ces implants zircone après 2 ans de suivi, de recueillir des informations sur l’intégration tissulaire des implants et de rechercher les facteurs de risque d’échec des implants en Zircone. Matériel et méthode : l’étude ZIR-ROC a été menée dans le service de chirurgie orale du CHU de Montpellier sur des implants monobloc en Zircone de la société Paris Implant®. La pose de 43 implants a été déterminée pour permettre l’analyse statistique des résultats. Le forage et l’insertion des implants ont été réalisés à l’aide du système de chirurgie guidée 2ingis®. La variable principale pour évaluer l’ostéo-intégration des implants a été le score délivré par le Periotest®. 22 variables secondaires ont été recueillies tels que les indices gingivaux et de plaque ainsi que l’analyse rétro-alvéolaire. Les données ont été relevées juste avant la chirurgie implantaire, ainsi qu’à 1 semaine, 4 semaines, 5 mois, 1 an et 2 ans. La méthode de Kaplan-Meier, le modèle de Cox et les analyses en composantes principales ont été utilisés pour l’analyse statistique. Résultats : Tous les implants ont présenté une bonne stabilité primaire post-opératoire (valeurs du Periotest comprises entre -8 et +1 ; moyenne à -5,7). Le taux d’échec implantaire a atteint 31% après les 5 premiers mois d’ostéo-intégration. Une mobilité clinique a été observée pour les implants perdus. Les facteurs de risque décrits dans la littérature ont été retrouvés dans le modèle de Cox avec une significativité pour la consommation de tabac et d’alcool et sans significativité statistique pour la densité osseuse ou encore la mise en place d’une couronne provisoire. Par ailleurs, la présence de plaque et d’inflammation gingivale a été observée en faible quantité sur les implants en Zircone. Discussion et conclusion : Le Zircone apparaît comme un matériau biocompatible pour des implants dentaires. Les causes des échecs implantaires précoces observés sont probablement multiples et cette étude n’a pas permis de démontrer l’implication seule de la Zircone dans ces échecs. La recherche des facteurs d’échecs implantaires a conduit à évaluer la technique chirurgicale utilisée pour cette étude mais aussi le dessin de l’implant. De plus, une étude in vitro comparant des implants à base de Zircone et de Titane a été entreprise pour évaluer l’affinité de cellules souches d’origine dentaire pour les 2 matériaux
Introduction: Since first Bränemark dental implants were implanted, operative surgery and materials for implantation have evolved. Titanium was the gold standard for dental implant material. But others materials like Zirconium were studied in replacement of Titanium due to allergy, bio-integration end aesthetic reasons. Contributing risk factors of Titanium implant failure include oral hygiene, tabacco and early loading among others factors. Objective: The aim of this clinical study was to evaluate survival rate of Zircon implants after 2 years, to collect information for tissue integration of Zirconium implant and to identify risk factors for Zircon implant failure. Material and Methods: ZIR-ROC study, conducted in the Oral Surgery Departement in Montpellier University Hospital, used zircon monobloc (ZIR-ROC®) implants (Paris Implant Society®). 43 implants were required for statistical analysis. Drilling and implantation were conducted with 2ingis® surgical guide system. The Periotest® value was the first endpoint for the implant osseointegration analysis. Gingival and dental plaque indices as well as intraoral X-ray analysis were part of the 22 secondary variables. Data were collected just after implantation surgery, and then, 1 week, 4 weeks, 5 months, 1 year and 2 years after implantation. Kaplan-Meier method, Cox regression model and principal component analysis were used for statistical analysis. Results: All implants showed postoperative optimal primary stability (Periotest® values between -8 and +1; mean: -5,7). Implants failure rate reached 31 percent after the 5 initial months of osseointegration. Clinical mobility was observed for the failed implants. Risk factors published in the scientific literature were observed in the Cox regression model with significant statistical effect for tobacco and alcohol consumption but without significant statistical effect for osseous density or even temporary crown insertion. Furthermore, gingival inflammation and dental plaque presence were low on Zircon implant. Discussion and Conclusion: Zirconium remains a biocompatible material for dental implantation but there were probably many reasons for the observed early implant failures and this study could not demonstrate the only involvement of Zirconium based material. Operative surgery used in this clinical study and the design of the implants were studied for researching other risk factors. In addition, an in vitro study comparing Zirconium versus Titanium as gold standard, was conducted for testing affinity of dental stems cells on Titanium and Zirconium-based dental materials

U/Pb and (U-Th)/He (ZHe) dating of detrital zircons from glacial till samples in the Ross Embayment, Antarctica records cooling after the Ross/Pan-African orogeny (450-625 Ma) followed by a mid-Jurassic to mid-Cretaceous heating event in the Beacon basin. Zircons were extracted from till samples from heads of major outlet glaciers in East Antarctica, one sample at the mouth of Scott Glacier, and from beneath three West Antarctic ice streams. The Ross/Pan-African U/Pb population is ubiquitous in these Antarctic tills and many Beacon Supergroup sandstones, thus 83 grains were analyzed for ZHe to subdivide this population. Two ZHe age populations are evident in East Antarctic tills, with 64% of grains 115-200 Ma and 35% between 200-650 Ma. The older population is interpreted to be associated with the Ross/Pan-African orogeny including cooling of the Granite Harbour Intrusives and/or exhumation of the older basement rocks to form the Kukri Peneplain. The lag time between zircon U/Pb, ZHe and 40Ar/39Ar ages from K-bearing minerals show cooling over 200 My. Grains in East Antarctic tills with a ZHe age of 115-200 Ma likely reflects regional heating following the breakup of Gondwana from the Ferrar dolerite intrusions, subsidence within the rift basin, and a higher geothermal gradient. Subsequent cooling and/or exhumation of the Transantarctic Mountains brought grains below the closure temperature over a span of 80 My. This population may also provide a Beacon Supergroup signature as most of the tills with this age are adjacent to nunataks mapped as Beacon Supergroup and contain an abundance of vi Beacon pebbles within the moraine. Nine zircons grains from three Beacon Supergroup sandstones collected from moraines across the Transantarctic Mountains yield ages from 125-180 Ma. West Antarctic tills contain a range of ZHe ages from 75-450 Ma reflecting the diverse provenance of basin fill from East Antarctica and Marie Byrd Land. ZHe and U/Pb ages <105 Ma appear to be distinctive of West Antarctic tills. The combination of U/Pb, ZHe and 40Ar/39Ar analyses demonstrates that these techniques can be used to better constrain the tectonic evolution and cooling of the inaccessible subglacial source terrains beneath the Antarctic Ice Sheet.

ZrO2 fibers has high-temperature-resistant property and anti-corrosion propertie, it can be used in chemical, aerospace and other areas of special environments. Currently, the main manufacturing technology of ZrO2 fiber is controlled by the United States, Britain and other developed countries, our country's manufacturing standards have a large gap between foreigners'. So, imported ZrO2 fibers and its products are expensive. Therefore, manufacturing high performance nano-ZrO2 ceramic fiber and studying the insulation performance, have important significance. ZrOCl2/PAN composite nanofibers with different structures were prepared by electrospinning, ZrO2 ceramic nanofibers was fabricated through calcinations. The microstructure of ZrOCl2/PAN composite nanofibers were characterized using scanning electron microscopy (SEM). Thermogravimetry (TGA) was used to analysis the thermal stability of ZrOCl2/PAN composite nanofibers and the calcining process of nanocomposites. The crystal structure and composition of ZrO2 ceramic nanofibers are characterized by X-ray diffractometry (XRD) and Fourier-Transform Infrared Spectrometer (FT-IR). The main conclusions are following: ZrOCl2/PAN composite nanofibers with ZrOCl2 of 10% have the best unformity, the average diameter of fibers is about 107.2 nm, and the fiber diameter distribution was narrow. In the sintering process, organic was removed, the structure of ZrO2 was keeping fiber stucture, because ZrO2 nuclei are growing on the basis of before ZrOCl2/PAN nanofibers, direction and structure. When the sintering temperature increasing, ZrO2 particles become larger, the structure of ZrO2 fibers are being destroyed for monoclinic and tetragonal mutual was transforming and ZrO2 grains are expanding or shrinking constantly. So, getting ZrO2 nanofibers with high-performance, the sintering temperature is the key. ZrO2 ceramic nanofibers concentrated at 700 °C was the monoclinic phase mixed with tetragonal phase. The average diameter of ZrO2 nanoparticles is only 10.6nm. ZrO2 ceramic nanofibers could improve the radiating performance of the composite material.

Three chapters about dental materials were investigated in this study. 1.Properties of investment for precision castings The aim of this chapter was to investigate the properties of investment for precision castings. The results indicated that the thermal expansion of investment Gilvest Ti is small, but the setting expansion is large enough to compensate the shrinkage of titanium casting. Besides, its thermal expansion at T ³ 600 ℃ was constant and its heating-cooling cycle was almost reversible. These two results can also reduce the thermal shock and then avoid the cracking of investments. 2.Properties and structures of electrolytic ZrO2 coating on dental Co-Cr alloys This study was conducted to increase the corrosion resistance and to decrease the metal ion release of dental cobalt-chromium alloys by electrolytic ZrO2 thin coatings. The microstructure of electrolytic zirconia coated films on Co-Cr substrates were also examined. The AAS’s results show that the ZrO2 coated Co-Cr alloys decrease the chromium ion level than that of uncoated Co-Cr alloy. According to the results of ESCA, the bonding energies of ZrO2 coating surface layer which changed with the annealing temperature from 400 oC, 500 oC to 600 oC are attributed to amorphous (a), tetragonal (t), and monoclinic (m) structure, respectively. The X-ray diffraction (XRD) of the coatings on the Co-Cr substrates annealed at 400, 500 and 600 oC revealed the major crystallization from m through t and then to m + t. However, the TEM observations clearly showed that the interface layer of the coatings was nanosize crystallites, first the formation of monoclinic and then with tetragonal ZrO2 structures. These different phase transformations are mainly due to different surface energy of ZrO2 coating in air, in bulk or on Co-Cr alloy. 3.Corrosion resistance of ZrO2 coating on cast titanium in fluoride containing solution. Zirconia coatings were formed on pure titanium by electrolytic deposition. The aim of this chapter was to investigate the effect of electrolytic zirconia coating on the corrosion resistance of cast titanium in fluoride containing solution. The dynamic polarization curves indicated that titanium and ZrO2 coated specimen showed good resistance in artificial saliva and the latter is better. However, the corrosion resistance of uncoated and coated titanium was decreased with increasing the concentration of fluoride in artificial saliva. Also, the corrosion resistance of titanium and ZrO2 coated specimen was decreased seriously in high concentration of NaF and low pH value artificial saliva because HF was formed in acidic NaF solution.

Zirconia ceramic element is one of the main parts of the Oxygen sensor. Its surface needs especially protective layer. In the early period, people always used the flame spray method to coat a protective layer on the surface of the ceramic element to protect its external platinum layer. Recently, based on the breakthrough of the protective layer slurry technology, a new wet coating technology has been invented and replaced the flame spray method. However, due to the quantity and quality requirement of the production, an automatic coating system becomes necessary to replace the present manual tasks. In this point of view, we have firstly studied the manual coating procedures, and applied TRIZ theory to improve the process and design an automatic coating system. The research also used the Taguchi method to find out the optimum working parameters, and verified the production capability of the automatic system. The main result of this study is the development of the automatic coating system for the ceramic element, which is very useful for the manufacturer to carry out their mass production.

Abstract (sommario):

Alumina to Zirconia is a history of the CSIRO Division of Mineral Chemistry, and tells the story of a significant part of Australia's mineral heritage. This history draws on the authors' long associations with the Division, anecdotal material, scattered records and photographs. What unfolds is a fascinating history of the Division of Mineral Chemistry, from its war-time origins as the Minerals Utilization Section in 1940, through several organisational changes under the guidance of four chiefs, until the end of 1987, when the name of the Division was changed to Mineral Products. In telling the story, Dr Joy Bear and her co-authors outline many of the main projects undertaken, highlight the achievements as well as the difficulties encountered in both the scientific and technological research itself, and in the commercialisation of newly developed processes. They also acknowledge the vital contributions of support staff, and acknowledge the close association of the Division with, and the contribution to research by, the Australian minerals industry. This is a story of scientific and technological achievement of the highest order. Alumina to Zirconia is essential reading for all those interested in the history of Australian science and its role in supporting the development of Australia's world class minerals industry.

Abstract (sommario):

The object of our research is the Kazantip Cape (Kerch Peninsula, Crimea). Its attraction is a ring-shaped rock massif composed of bryozoans previously considered to be a reef structure growing on the limbs of rising brachyanticline about 8 million years ago. Application of complex of investigating methods show that clay deposits underlying bryozoan structure are composed of expandable mixed-layered minerals, smectite, kaolinite, chlorite, illite with accessory minerals (zircon, monazite, ilmenite). These clays are the result of eruption of fossilized analogue of mud volcano. This process was accompanied by unloading of cold gas-fluid seepage. Specific mineralization (barite, celestine, strontianite, authigenic minerals of rare-earth elements and manganese) of bryozoan’s bioherms indicates that the seep process continued even after the waning of mud volcanism.

The article is devoted to environmental aspects of ceramic brick production using non-ferrous metallurgy waste. Studies show that the use of polymetallic ore dressing as a tailing agent and the tails of gravity of zircon-ilmenite ore as a plasticizing part makes it possible to obtain ceramic bricks with improved technical characteristics, eliminating the use of traditional raw materials. The study used regression analysis, with the help of which mathematical models were obtained that were not included in the series of the experiment of ceramic masses
