摘要
采用熔制法制备两种可析出不同晶相的CaO-MgO-Al2O3-SiO(2CMAS)玻璃,研究了不同原料组成下CMAS玻璃的析晶行为和显微结构。研究结果表明,CMAS玻璃A在986℃下热处理4 h,能析出钙长石和透辉石主晶相;CMAS玻璃B在950℃下热处理4h,可获得堇青石晶相及少量金红石型TiO2晶相。
CaO-MgO-Al2O3-SiO2 （CMAS） glass ceramics with two crystallites were prepared by the melting method. The crystallization and microstructure of CMAS glass ceramics prepared with different raw materials were studied. Results show： the main crystalline phases of CMAS glass ceramic sample A obtained after 4 h thermal treatment at 986℃ are anorthite and diopside; 4 h thermal treatment of CMAS glass ceramic sample B at 986℃ can produce cordierite and a small amount of rutile phase TiO2 crystals.
