【摘要】 在Ｌｉ２Ｏ－ＣａＯ－Ａｌ２Ｏ３－ＳｉＯ２系统中加入ＺｒＯ２，ＴｉＯ２作为晶核剂，制得的微晶搪瓷具有高硬度、高耐磨性及高抗冲击强度。测定了该微晶搪瓷的某些性能，并借助Ｘ－射线衍射仪及扫描电子显微镜，观察和分析了存在于微晶搪瓷中的晶体的种类及其形貌，并讨论了几个有关的问题。更多还原

【Abstract】 The vitro-microcrystalline enamel based on Li2O-CaO-Al2O3-SiO2 system with additive ZrO2,TiO2 as nucleating agent is of high hardness, wear resistance and impact resistance. Some properties of this enamel were measured, and its microstructure was examined by using X-ray diffraction and SEM. Some discussions were carried out in this paper.更多还原
