摘　　要：本文研究了以铁尾矿为主要原料制备微晶玻璃材料的方法 ,根据微晶玻璃的基础组成 ,选择 Ca O- Mg O- Al2 O3 - Si O2 系统做为配方依据 ,制成了透辉石型黑色尾矿微晶玻璃。用 DTA、XRD和 SEM分析了该材料的晶相和显微结构 ,并对其主要理化性能进行了测试 ,为综合利用尾矿资源生产高附加值产品开辟了一条途径。Methods of manufacturing glass-ceramics with metallic tailings as major raw materials were described in this article.According to chemical composition of the glass-ceramics,the formula for glass mixture was selectedamong CaO-MgO-Al 2O 3-SiO 2 system,and the black architectural glass-ceramics that predominant phase is diopside is gotten.Phase identification and microstructure examination was done using DTA,XRD and SEM.Major physical and chemical properties of the glass-ceramics were tested.A new way is started for developing high added value products from comprehensive utilization of the metallic tailings.
