Aluminosilicate (LAS) glass-ceramics (GC) finds use in many high-tech applications, e.g., motor pistons and telescope mirrors etc. due to its ultra-low thermal expansion coefficient (ULTEC). The crystallization of lithium aluminosilicate glass ceramics was investigated by different techniques including differential thermal analysis and X-ray diffraction. β-quartz solid solution phase in the Li2O-Al2O3-SiO2-P2O5 glass system has been precipitated by controlled heat-treatment of the parent glass prepared by melt-quench technique which has been confirmed by XRD analysis of heat-treated material.
