摘要

用扫描电镜、X射线衍射仪、金相显微镜等测试手段

研究了采用不同孔径MgO泡沫陶瓷过滤粗Mg前后组织形貌的变化。结果表明

随着泡沫陶瓷过滤孔径的减小

残余的夹杂物更少、更小

而且密度更接近于Mg的理论密度。但经不同孔径泡沫陶瓷过滤的Mg晶粒都比较粗大

而且所得的纯Mg是由α-Mg相组成

没有共晶相。

Abstract

Influences of MgO ceramic foam filter with different apertures on structures and properties of magnesium were observed by SEM （scanning electron microscope）

XRD （X-ray diffraction） and metallurgical microscope. The results show that residual inclusion is decreased greatly and the density of crude magnesium filtered can gradually be tended to theory density with decreasing in filter apertures

while grain sizes of the magnesium filtered are increased

meanwhile

absence of eutectic phase can be observed.
