摘　　要：运用静态实验的方法,以尾矿玻璃熔体对碳化硅和二硅化钼耐火材料进行了侵蚀试验.利用X射线衍射、扫描电镜等方法,对侵蚀前后的耐火材料的晶相组成和显微结构进行了研究,探讨了尾矿玻璃对耐火材料的侵蚀机理.实验结果表明:尾矿玻璃对耐火材料的侵蚀是一个复杂的物理化学过程,耐火材料不仅受到玻璃液的物理侵蚀,同时还受到其化学侵蚀.Static experiments on the corrosion of tailing glass melt to silicon carbide and silicon molybdenum refractories were made. The crystalline composition and microstructure of these refractories before and after being corroded were investigated by XRD and SEM. The corrosion mechanism of tailing glass to these refractories was discussed. The experimental results show that the corrosion of slag glass to refractories is a complex physical chemisty process. These refractories are attacked both physically and chemically by glass melt.
