摘要
本文研究了SiO_2-MgO-MgF_2-K_2O系统四硅氟云母微晶玻璃的制备工艺,通过热膨胀曲线、差热分析及扫描电镜观察,探索了微晶玻璃的热处理制度,用x-ray衍射方法确定了晶类及结晶率,并对材料的半透明性能作了理论探讨。
The preparation procedure of glass--ceramics containing tetrasilicic mica was searched for in the system based on K_2O--MgO--MgF_2--SiO_2. Heat trcatment procedure was deter- mined by the analysis of thermal expansion. DTA and SEM.The type of crystal and amount of crystal were determined by XRD.The translucely property of glass--ceramic was discussed in theory
