磷灰石(APA)可铸造陶瓷的晶化特性

The Crystallization Feature of a Castable Apatite Glass-ceramics

本文采用差示热分析（DTA），X射线衍射（XRD）、扫描电镜（SEM）等方法研究了磷灰石可铸造陶瓷的晶化特性，并就化学组成对微观结构的影响进行了讨论。MgO及Al2O3的引入对磷灰石激晶玻璃的晶化特性有重要影响。

The crystallization feature of a castable apatite glass-ceramics was studied by the means of DTA,XRD and SEM. The effect of chemical composition on the microsturcture of the glass-ceramics was discussed. Theintroducti0n 0f MgO and Al2O3 into the system has a substantial influence on the crystallization feature.
