High Purity Refractory Silica Firebrick for Coke Oven Batteries
Product Introduction:
Silica brick is an acid refractory material composed of tridymite, cristobalite and a small amount of residual quartz and glass phase. Silica bricks have good resistance to acid slag erosion. The refractoriness under load is as high as 1640~1670ºC, and the volume is relatively stable under high temperature for long-term use.
