摘　　要：由于熔融石英砖的热膨胀系数小,它在玻璃熔窑上被作为热修补材料使用,从而也存在和其它耐火材料一样被侵蚀,引起蚀变,并在玻璃液中产生疵点的现象。本文从几个典型的侵蚀样品的岩相分析中,试图揭示其变化过程及特点。The fused quartz brick is used as hot repair materials of glass furnace because of its low thermal expansion coefficient . It is also as easily attacked by high temperature melt as other refractory. The drop of attacked brick can bring point defect in glass . This article illustrated the corrosion process and characteristics of fused quartz brick by petrographic examination on several typical attacked samples .
