Anisotropic residual stresses in partially crystallized Li2O±2SiO2 glass-ceramics
Levels of residual stresses in partially crystallized Li2O±2SiO2 glass-ceramics were calculated for several crystallographic planes. The stresses were also determined by an X-ray diraction method (XRD) using synchrotron radiation. The linear thermal expansion coecient (ahkl) of a fully crystallized, stress-free, powdered sample, was measured in situ using a hot-stage XRD technique. The therma...
متن کاملIon-Exchange in Glass-Ceramics
In the past few years, ion-exchange (IOX) in glasses has found a renewed interest with a lot of new development and research in industrial and academic labs and the commercialization of materials with outstanding mechanical properties. These glasses are now widely used in many electronic devices, including hand-held displays and tablets. The exchange is generally conducted in a bath of molten s...
متن کاملMicrostructure and Properties of Li2O-Al2O3-SiO2-P2O5 Glass-Ceramics
Serials Li2O–Al2O3–SiO2 matrix glasses and glass-ceramics with different content of P2O5 were prepared by conventional melt cooling method and crystallization process. The effects of P2O5 content on microstructure and properties such as viscosity, melting temperature and coefficient of thermal expansion (CTE) of Li2O–Al2O3–SiO2–P2O5 glasses and glass-ceramics were investigated by DSC, XRD, CTE ...
متن کاملMicrostructure 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 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...
