The crystallisation characteristics of glasses based on the Li2O–CaO–SiO2-Al2O3(LCSA) system containing TiO2, ZrO2 has been investigated by differential thermal analysis (DTA), X-ray diffraction analysis (XRD), and scanning electron microscopy (SEM). The partial replacement of Li2O, CaO and SiO2 by TiO2, ZrO2 in the studied glass-ceramics led to the development of different crystalline phase assemblages, including lithium calcium silicates, wollastonite, a-eucryptite and a-spodumene using various heat-treatment processes. The rod-like growth morphology was observed by SEM for glass free of TiO2. In this glass, ZrO2 reduced mobility of boundary at sintering temperature, 1000°C and relatively density was 77%. The most sinterability observed in sample containing TiO2 and free of ZrO2 at sintering temperature, 1000°C and relatively density was 84%.
