Addition of Alumina to Nanoporous Calcium Titanium Phosphate Glass-Ceramics and its Effects on Crystallization Behavior
Microporous Calcium Titanium Phosphate glass-ceramics have many uses in high-tech industries. For example, they have applications in catalysts industry. In this study, different molar percentages of alumina were added to a glass with P2O5 30, CaO 45, TiO2 25 (mol%) composition. The samples were melted at 1350°C and crystallization heat treatment was performed on...
متن کامل-doped chalcogenide glass-ceramics based on selenium
Rare earth doped glass-ceramics transparent in the infrared region up to 16 μm have been prepared and studied. The enhancement of the emission of Er 3+ ions at 1.54 μm with increasing crystallinity was demonstrated in a seleniumbased glass-ceramic having a composition of 80GeSe2-20Ga2Se3+1000 ppm Er. The optical transmission, microstructure and luminescence properties of a base glass and glass-...
متن کاملMagnetoelectric Effect in Ceramics Based on Bismuth Ferrite
Solid-state sintering method was used to prepare ceramic materials based on bismuth ferrite, i.e., (BiFeO3)1 - x -(BaTiO3) x and Bi1 - x Nd x FeO3 solid solutions and the Aurivillius Bi5Ti3FeO15 compound. The structure of the materials was examined using X-ray diffraction, and the Rietveld method was applied to phase analysis and structure refinement. Magnetoelectric coupling was registered in ...
متن کاملSynthesis and Structural Studies of Er3+ Containing Lead Cadmium Fluoroborate Glasses and Glass-Ceramics
A partir de resultados de experimentos de fusão e choque térmico, o domínio vítreo foi identificado no sistema PbF 2 -CdF 2 -B 2 O 3 . Vidros puros e dopados com Er foram preparados e vitrocerâmicas foram obtidas a partir de tratamentos térmicos adequados. A fase cristalina foi identificada como PbF 2 . Estudos estruturais foram efetuados por difração e absorção de raios X e o papel desempenhad...
متن کاملIron Phosphate Glass-ceramics
The crystallization of 40Fe2O3-60P2O5, 10ZnO-30Fe2O3-60P2O5 and (43.3−x)PbO–(13.7+x)Fe2O3–43P2O5, (0 < x < 30), glasses and glassceramic have been investigated. The structural evolution of glasses during heat treatment at various temperatures and the tendency for crystallization for series of glasses with modified composition are characterized by a dendrite-like phase separation in the early st...
