摘要 文章以Li2O-ZnO-SiO2系统为基础玻璃组成,通过DTA、XRD及热膨胀系数等测试手段,分别对添加Na2O或K2O的微晶玻璃的结晶行为和热膨胀变化规律进行了研究探讨。结果表明,成分中碱金属会影响高热膨胀相方石英微晶体的析出。 This paper composes glass on the basis of System Li2O-ZnO-SiO2,researches and discusses respectively about the crystallization behavior and variation law of thermal expansion of the glass-ceramics that is added Na2O or K2O.The result shows that alkali metal will affect the crystallization of high thermal expansion quartz micro crystal.
