摘　　要：介绍了以钢渣、粉煤灰、铜尾矿及砂岩为主要原料制备微晶玻璃的方法。利用DTA、XRD、SEM及EDS等方法研究了微晶玻璃的热处理制度;确定其主晶相为透辉石及其晶相组成成分;晶粒形貌为颗粒状,晶粒的尺寸约为0.5μm。实验结果表明:当废渣及工业砂岩引入为90%时,主晶相为透辉石,材料结构均匀致密、性能良好。实验热处理制度工艺参数为:退火温度:550℃,保温1h;晶化温度900℃,保温2h。The method of manufacturing glass ceramics with steel slag, fly-ash, copper mine tailings and sandstones as major materials was described. Heat-treatment parameters, major phase of crystallization, and composition and pattern of crystallized particles were used by DTA, XRD, SEM and EDS. The result of experiment was tested：when multi-solid waste slag was introduced into 90 percent, the major phase of crystallization is diopside, which is characterized with homogeneous, dense structure and excellent performance. The optimal heat treatment parameters： annealed temperature is at 550℃ for 1 hour and crystallized temperature is at 900℃ for 2 hours.
