摘　　要：通过烧结法制得CaO-Al2O3-SiO2系统微晶玻璃样品,对样品进行了化学分析、X-射线衍射分析、扫描电镜分析和偏光显微镜分析,确定其主晶相为硅灰石(CaSiO3),晶粒形貌为棒状、柱状,晶粒大小为0.2～0.3μm,晶相含量为35%～40%。The CaO-Al_2O_3-SiO_2 glass-ceramics samples obtained by sintering at low temperatures have been analyzed by chemical analysis, XRD, SEM. The results show that dominant crystalline phase is wollastonite (CaSiO_3),and the shape of the wollastonite crystals is neadle-like and their sizes are 0.2-0.3μm,as well as the content of the crystals is within 35%-40%.
