High quality silica brick
Silicon brick is the acid refractory mainly composed of tridymite, cristobalite, and a small amount of residual quartz and glass phase. The silica content accounts for more than 96%, which lead to the high acid slag erosion resistance, high temperature resistance, and high deformation resistance in high temperature for long term use.
Product Purpose
Silicon brick is mainly used in the coke oven of metallurgy, building materials, light industry, chemical industry, electronics and other industries, the large wall chest wall, regenerator roof, target wall and other parts of blast furnace and glass furnace.
