摘　　要：以唐钢高炉渣为主要原料，分别加入Cr2O3、TiO2、Fe2O3、P2O5形核剂以及一定配比的其他成分的原料，采用熔融的方法制备高炉渣微晶玻璃。利用差热分析仪、电子扫描显微镜来研究不同形核剂对微晶玻璃析晶行为的影响。结果表明：高炉渣中添加2%Cr2O3，8%P2O5形核剂可以实现体积析晶，形成晶粒细小、分布均匀的微晶玻璃，添加8%TiO2、6%Fe2O3时是表面析晶，不能形成理想的微晶玻璃。Taken Tangshan iron and steel blast furnace slag as the main raw material, Cr203, TiO2, Fe203 and P205 nucleating agent had been added with a certain proportion of other raw materials, and the blast furnace slag microcrystalline glass had been prepared by melting method. Differential thermal analyzer （SEM） and electron scanning microscope （SEM） were used to investigate the effect of nucleating agents on the crystallization behavior of glass ceramics. The results show that 2% Cr203 and 8% P205 can form microcrystalline glass with fine grain and uniform distribution. Addition of 8% TiO2 and 6% Fe203 can not result in an ideal microcrystalline glass.
