Le, Coz Alexandre. "Investigation de nouveaux matériaux céramiques transparents dans l’infrarouge". Electronic Thesis or Diss., Université de Rennes (2023-....), 2023. http://www.theses.fr/2023URENS119.
This work focuses on the development of new infrared transparent sulfide and oxysulfide ceramic materials for passive optics applications. A combustion synthesis method is used to produce BaLa₂S₄ and La₂O₂S precursor powders. Sulfurization treatment under H₂S or H₂S/H₂ at high temperature is required to obtain very high purity powders. Various sintering methods have been used to densify the ternary sulfide BaLa₂S₄ : hot pressing and natural sintering under H₂S followed by hot isostatic pressing. The latter technique allows the elaboration of infrared transparent BaLa₂S₄ ceramics. However, transparency is limited by absorption bands associated with the presence of residual oxygen. La₂O₂S powders are densified by hot-pressing. A density of over 99 % is achieved in only 2 h-sintering. Significant optimization of powders morphology is achieved through ball-milling leading to improved optical performances. The transparency window extends from 1 to 10 µm, with a theoretical maximum transmission reached around 7 µm. Further work is required to maximize transparency at short wavelengths to consider active optics applications

The techniques of ultrafast pressureless sintering as microwave or induction sintering offer manyadvantages. However, the development of these techniques requires an understanding and a control ofthe mechanisms involved. Both similar and complementary, these processes of heating-sintering havebeen studied by an experimental approach to increase knowledge in the field of Ultrafast PressurelessSintering.In this thesis, the study of microwave sintering of Al2O3-(Y)ZrO2 composites has been conductedin parallel with induction sintering of a submicronic nickel powder. The experimental approach usedconsisted in carrying out sintering experiments at imposed heating rates (from 25 to 1000°C/min) onchosen materials and small parts, referring to conventional sintering behavior at the macroscopic andmicroscopic scale
Gajdowski, Caroline. "Élaboration de spinelle MgAl2O4 transparent par frittage naturel et post-HIP pour des applications en protections balistiques". Thesis, Valenciennes, 2018. http://www.theses.fr/2018VALE0022/document.
This work focuses on the improvement and the lightening of transparent ballistic armours. The conventional use of glass provides high efficiency against a projectile, however associated with a heavy and thick armour. The replacement of the strike face by a polycrystalline ceramic, such as MgAl2O4 spinel, leads to a performance gain and a decrease of the protection volume. The development of this material requires the combination of a high optical quality in the visible domain and high mechanical properties. In this work, pressureless sintering under vacuum of a high purity commercial powder allowed to minimize the addition of impurities, detrimental to the transparency, and the grain growth phenomenon. An additional step of hot isostatic pressing was necessary to eliminate residual porosity and to obtain transparent spinel with high optical quality (80% at 400-800 nm, t = 2 mm, Ø21 mm). An analysis of the microstructure before and after the post-treatment made it possible to determine the link between the grain and pore sizes before post-sintering and the observed grain growth during this treatment. An optimisation of the process was established in order to restrain the grain size increase, and thus to obtain a homogeneous microstructure (~ 12 μm). After a successful up-scaling of the samples (t = 4 mm, Ø60 mm), several spinel samples with distinctive microstructural and mechanical properties were selected in order to evaluate their performances through ballistic tests

In this work barium titanate doped with calcium and zirconium (BCTZ), with the composition Ba₀⋅₈₅Ca₀⋅₁₅Ti₀⋅₉₀Zr₀⋅₁₀O₃, was synthesized by solid-state route. The aim of this work was to elaborate an optimized and reproducible synthesis and sintering procedure. Besides, the composition was slightly varied to find the best compromise between the Curie temperature and the electrical properties. A decrease of the zirconium amount in this material led to an improvement of the Curie temperature associated to a decrease of the electrical properties. A solubility limit of 20 %at for calcium in BCTZ was demonstrated. Solid-state route coupled with conventional sintering proved to be an efficient process to obtain BCTZ samples with good properties but it is an energy and time-consuming process. By using microwave heating, the sintering step duration could be drastically reduced. Higher converse piezoelectric constant (d₃₃*) was measured for samples obtained by this fast sintering method. Microwave heating was also tested both to synthesize and to sinter BCTZ. Samples with a 88 % relative density and a d₃₃ piezoelectric constant of 50 pC/N were obtained in only 90 minutes
