Effects of CaF2 vis-a-vis TiO2 as nucleating agent in SiO2–Al2O3–CaO glass-ceramics
Abstract: The independent effects of CaF2 and TiO2 on the glass-ceramics based on SiO2–Al2O3–CaO system have been investigated. The crystallization behavior, microstructure, mechanical properties and chemical resistance of the glass-ceramics were studied by Differential Thermal Analysis (DTA), Scanning Electron Microscopy (SEM), X-ray diffraction (XRD), FTIR, mechanical and chemical resistance measurements. The CaF2 containing glass ceramics are found to be much superior to that of TiO2 containing glass ceramics on the basis of sintering strength, mechanical and chemical properties.
