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CaO-MgO-Al2O3-SiO2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-Al2O3-SiO2 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.
