【摘要】 CaO-Al₂O₃-SiO₂ 系统微晶玻璃作为微晶玻璃中的一个新品种,具有非常鲜明的特点。本文讨论了在CaO-Al₂O₃-SiO₂ 系统微晶玻璃中加入ZrO₂,研究了ZrO₂ 对CaO-Al₂O₃-SiO₂系统微晶玻璃烧结的影响。随着ZrO2 加入量的增加,玻璃颗粒的烧结收缩率下降,说明ZrO₂ 的加入对玻璃颗粒的烧结收缩有一定的阻碍作用。ZrO₂的加入对CaO-Al₂O₃-SiO₂ 系统微晶玻璃中的主晶相（β-硅灰石晶体）的析出没有大的影响。更多还原

【Abstract】 Being a new variety, CaO-Al₂O₃-SiO₂ glass-ceramic is outstandingly characterized and widely used. This paper discusses the addition of ZrO₂ into CaO-Al₂O₃-SiO₂ glass-ceramic and the influence of ZrO₂ on sintering process of CaO-Al₂O₃-SiO₂ glass ceramics. As the ZrO₂ increases, the shrinkage ratio of glass particle will decrease. Such phenomenon indicates that ZrO₂ has a baffling effect on sintering shrinkage ratio of glass particle. Increase of sintering temperature significantly conduces to descending the liquid phase viscosity of glass particles, which consequently is available for sintering. The addition of ZrO₂ has little effect on crystallization of main crystalline phase （β- wollastonite）.更多还原
