摘要
在Ｌｉ２Ｏ－Ａｌ２Ｏ３－ＳｉＯ２三元玻璃系统中，加入晶核剂ＴｉＯ２、ＺｒＯ２，通过热处理，制备出了主晶相为β－石英固溶体的透明微晶玻璃。用Ｘ射线衍射、ＳＥＭ对样品进行了分析。测定了玻璃热膨胀系数，并和原始玻璃作了对比，讨论了热处理制度、结构与性能之间的关系。
Transparent glass ceramics are prepared by heated treatment and adding nuclei TiO 2 and ZrO 2 in the ternary system Li 2O Al 2O 3 SiO 2.The main crystalline of glasses is β SiO 2 solid state.The samples were analysed using XRD and SEM,and the coefficients of thermal expansion were measured,compared with basic glass.The relations between heated treatment,structure and properties are discussed.
