Testo completoA substituição parcial de íons Fe3+ por pares de íons (Co2+-Ti4+ ou Co2+-Sn4+) na ferrita de bário hexagonal (BaFe12O19) leva a uma substancial diminuição no campo coercitivo (Hc) com uma pequena mudança na magnetização de saturação (Ms), permitindo seu uso em gravação magnética e magneto-óptica de alta densidade. Os diferentes métodos de preparação de ferritas de bário resultam em produtos com propriedades distintas. Neste trabalho, preparou-se BaFe12-2xCoxTixO19 e BaFe12-2xCoxSnxO19 (0,25 £ x £ 1) por coprecipitação, utilizando cloretos dos metais precursores e solução de KOH/K2CO3 como precipitante. Após a secagem, o produto obtido foi calcinado a 950oC por 3h, lavado e seco. Os difratogramas de raios X indicaram a formação da ferrita de bário. As micrografias eletrônicas de varredura mostraram que os pós obtidos apresentam-se na forma de plaquetas hexagonais de 1 a 2mm. As curvas de magnetização das ferritas de bário dopadas mostraram que o campo coercitivo e a remanência diminuem em função do aumento da razão de substituição x. A curva de magnetização da amostra dopada com Co-Ti, com x = 1 é característica de uma ferrita mole, com Hc = 13,5 kA.m-1 (0,17 kOe), Ms = 46,1 emu.g-1 e Mr = 11,0 emu.g-1. Para a amostra dopada com Co-Sn a diminuição de Mr não é significante. Estes resultados mostraram que as propriedades magnéticas das ferritas de bário dopadas obtidas por coprecipitação foram melhoradas, em relação aos dados da literatura para ferrita de bário pura ou dopada.
The partial substitution of Fe3+ ions with pairs of ions (Co2+-Ti4+ or Co2+-Sn4+) in hexagonal barium ferrite (BaFe12O19) leads to a substantial reduction on coercivity (Hc) with only a low change in saturation magnetization (Ms), allowing its use in high density magnetic and magneto-optical recording. Different preparative methods result in barium ferrites with distinguished properties. In this work, BaFe12-2xCoxTixO19 and BaFe12-2xCoxSnxO19 (0.25 £ x £ 1) were prepared by the coprecipitation method using chloride salt precursors and KOH/K2CO3 solution. After drying, the powder was calcinated at 950oC by 3 h, washed and dried. The X ray diffraction patterns indicated the barium ferrite phase formation. The scanning electron micrographs showed that the particles are hexagonal platelike with diameter size ranging from 1 to 2 mm. The magnetization curves of substituted barium ferrites showed that the values of Hc and Mr decrease with the increase of the substitution ratio x. The magnetization curve profile for Co-Ti substituted sample with x =1 is characteristic of a soft ferrite with Hc = 13.5kA.m-1 (0.17 kOe), Ms = 46.1 emu.g-1 and Mr = 11.0 emu.g-1. These results indicated that the magnetic properties of substituted barium ferrites obtained by coprecipitation were improved when compared with the literature data for pure and substituted barium ferrite.
Liu, Fanmao. "Photoresponse of ferroelectric BaTiO3 thin films". Doctoral thesis, Universitat Autònoma de Barcelona, 2017. http://hdl.handle.net/10803/458535.
Testo completoBaTiO3 is a lead-free ferroelectric oxide material. BaTiO3 thin films have been widely studied for memory applications due to its charge memory effect resulting from its ferroelectric nature. Nowadays, the scientific community has renewed its interest on BaTiO3, because it holds characteristics that is interesting for rapidly developing areas such as photovoltaics, photoelectric sensing and photocatalysis. The main goal of the present thesis is to study the photoelectric effects on BaTiO3 thin films and to give light on the relevant mechanisms that control them. Ferroelectric materials show intrinsic, unavoidable and exclusive internal electric fields: imprint electric field (Eimp) and depolarization electric field (Edep). Thus distinct photoelectric effects can be obtained due to Eimp and Edep. In the present thesis we have studied in detail the role of Eimp and Edep on photoelectric effects of BaTiO3 films. In particular, it is shown that appropriate measurement configuration can be used to disclose and isolate their contribution. As a result, different transient and constant photoresponses can be obtained as wish. By the same token, their contribution to the ferroelectric switching dynamics are also analyzed. The transient photoresponse finds its origin on the screening of surface charge (photoscreening). In order to modulate its magnitude detailed characterization has been performed. It is concluded that the polarization photoscreening is governed by the presence of water adsorbed at the surface, allowing it to be controlled. However, the photoelectric efficiency has been found to be limited by the low generation of carriers by light, that is the reason why the effect of O substituted by N in BaTiO3 lattice, which should result in band-gap narrowing, hence improving the photoelectric efficiency, has been studied. Interestingly, it is found that ammonia treatments are efficient to improve photoelectric responses, without having any clear evidence of N substitution.

Testo completoCom objetivo de determinar as características de atenuação do minério sulfato de bário (BaSO4) e do vidro cristal utilizados como blindagem contra as radiações ionizantes X e gama, em instalações radiográficas, foi realizado um estudo de atenuação com argamassa e concreto de barita, usados, respectivamente, no revestimento de paredes e em blocos; e com o vidro cristal usado em biombos e janelas. Para isso, foram analisadas 10 placas de argamassa de barita, 3 placas de concreto de barita, com área média útil de 900 cm2 e espessura média de 1 a 5 cm, e 3 placas de vidro cristal, com área útil de 323 cm2, com espessuras de 1, 2 e 4 cm. As amostras foram irradiadas com raios-X, com potenciais de 60, 80,110 e 150 quilovolts, e raios gama do 60Co. As respostas de atenuação (mGy/mAmin) e (mGy/h) ambos a 1 metro, em função da espessura, resultaram na obtenção das curvas de atenuação e de transmissão. Além disso, foram determinadas as espessuras equivalentes das camadas semi e deciredutoras, tanto para o vidro cristal, como para a argamassa e o concreto de barita

Testo completoUniversidade Presbiteriana Mackenzie
In this work were studied the action of ionizing radiation on the physical-mechanical properties in elastomeric compounds based on styrene-butadiene rubber (SBR) filled with barite, opening way for application of these composites in the protection and shield against high-energy radiation, in the form of aprons. These aprons come to substitute the elastomeric ones with lead filler in ergonomic and economically advantageous conditions. The effect of high-energy radiation was studied on SBR compounds filled with barite at 50, 75, 100, 125, and 150phr (phr = parts per hundred rubber) of barite concentrations, exposed to ionizing radiation at 0, 100, 200, 500 and 1000kGy doses. The samples were characterized by physic-mechanical tests as rheometry, tensile strength, resilience, hardness, wear resistance, oil absorption, permanent deformation under compression (compression set) and dynamic mechanical thermal analysis. The morphological characteristics were determined by scanning electron microscopy. The results showed that the radiation causes an increase in tensile strength and elongation, the tear strength and hardness, and a decrease in fluid absorção and deformation under compression.
Neste trabalho foi estudada a ação da radiação ionizante nas propriedades físico-mecânicas nos compostos elastoméricos a base de estireno-butadieno (SBR) carregados com barita, abrindo caminho para aplicação destes compostos na proteção e blindagem contra a radiação alta energia, na forma de aventais, vindo substituir os aventais a base de elastômero carregado com chumbo em condições ergonômicas e economicamente vantajosas. Foi estudado o efeito da radiação ionizante em compostos a base de SBR carregado com barita nas concentrações de 50, 75, 100, 125, e 150phr (phr = partes por cem de borracha) de barita expostos à radiação ionizante nas doses de 0, 100, 200, 500 e 1000kGy. As amostras foram caracterizadas por meio de ensaios físico-mecânicos de reometria, de resistência à tração, resiliência, dureza, resistência ao rasgo, absorção de óleo, deformação permanente sob compressão (compression set) e ensaios de análise térmica dinâmico-mecânica. As características morfológicas dos compositos foram determinadas por meio de microscopia eletrônica de varredura. Os resultados mostraram que a radiação provoca um aumento da resistência à tração, do alongamento sob tração, da resistência ao rasgamento e da dureza; e um decréscimo na absorção de fluido e na deformação sob compressão.
