Microstructure of Transparent Strontium Fresnoite Glass-Ceramics
Glass-ceramics grown from a glass of the composition Sr2TiSi2.45O8.9 (STS 45) are analyzed by scanning electron microscopy (SEM) and electron backscatter diffraction (EBSD). Oriented nucleation with the c-axes preferably perpendicular to the surface is detected. A very strong 001-texture is observed after only 10 μm of growth into the bulk, making this the first system in which an orientation p...
متن کاملThe Crystallization Effect on the Optical Properties of Oxyfluoride Glass-Ceramics Containing CaF2 Nanocrystals Doped with Y3+ Ions
In the present study, the oxyfluoride glasses of SiO2-Al2O3-CaF2 system containing different amounts of Y3+ ions were prepared through the convenient melting method. The crystallization temperatures and size of the CaF2 nanocrystals were obtained from DTA curves and XRD patterns, respectively. As a consequence, the optimum amount...
متن کاملProcessing of transparent glass-ceramics by nanocrystallisation of LaF3
ransparent glass-ceramics have been prepared by heat-treating oxyfluoride glasses in the Na2O–Al2O3–SiO2–LaF3 system. The nanocrystallisation f LaF3 was achieved by controlling time and temperature parameters. Glasses and glass-ceramics were characterised by dilatometry, DTA, XRD nd TEM. The mean crystal size (<20 nm) and the crystal fraction increase with the temperature of heat treatment, whi...
متن کاملDesign and Properties of Glass-Ceramics
The regenerator glass-ceramic is produced as a honeycomb product for a turbine engine heat exchanger. It is made from a powdered glass frit, which as a slurry can impregnate paper that is wound as alternately corrugated sheets on a wheel. After firing, a porous ceramic regenerator wheel is produced that allows energy to be transferred from hot exhaust gases to the cold intake air in the turbine...
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-...
