摘　　要：本文以铜渣为原料,采用熔融还原法先提取铜渣中的铁,同时将余渣经热处理转变成微晶玻璃。采用碳硫分析仪对还原提取的铁进行成分分析,其硅、磷、碳等达到炼钢要求,硫仍然超标。通过XRD测得铜渣微晶玻璃的主晶相为钙长石(CaAl2Si2O8),次晶相为镁黄长石(Ca2MgSi2O7),其晶粒的平均尺寸在150 nm左右,分布均匀。Glass-ceramics were prepared by the casting method using copper slag as a raw material. The composition of extracting iron analysis by carbon-sulfur analyzer, the silicon, phosphorus and carbon of steelmaking requirements, sulfur still exceeds standard. The microstructure of glass-ceramics was investigated by X-ray diffractometry and scanning electron microscope. Results show that main crystallization phase of glass-ceramic was anorthite, and the minor crystalhzation phase was akermanite.
