高纯度天然烧结镁砂中杂质成分的分布

Impurity content distribution of sintered magnesia made from high-purity natural magnesia

采用光学显微镜、扫描电子显微镜和能谱仪等研究了海城镁矿烧结镁砂的化学组成、显微结构及元素的分布，并由此推测出其质量情况。

In this paper,by use of the routine physical-chemical analysis,and optical microscope,scanning electronic microscope and spetrometer,the performances and microstructure distributive rule of elements in natural high-purity sintered magnesia were systematically studied and through those,the quality was predicated.
