摘　　要：采用熔融法制备微晶玻璃材料,探讨了钢渣微晶玻璃中引入ZrO2对其显微结构以及性能的影响。用X衍射仪和扫描电镜分析了微晶玻璃的主晶相和显微结构。实验结果表明:引入质量分数为1%的ZrO2时,微晶玻璃的晶粒最小,抗弯强度最大;当ZrO2的添加量进一步增多,晶粒无法发育完全且晶相含量下降,导致微晶玻璃的抗弯强度降低。在该钢渣微晶玻璃中,ZrO2最佳添加量的质量分数为1%。The glass-ceramics was prepared by melting method. The effect on microstructure and performance of glass-ceramics based on steel slag doped with zirconia was described. The crystalline phase and microstructure of the glass-ceramics were observed by XRD and SEM analysis techniques. The results showed that： when ZrO2 is 1% , the size of crystalline grains is minimal but the flexural strength of glass-ceramics is maximal. When the additive amount of ZrO2 further increases, crystalline grains can not grow well and the content of crystal decrease. The optimal amount of ZrO2 is 1%.
