Silica brick is made of silica (≥96%)as raw material, added mineralizer and binder, produced by the process of mixing, molding, drying and firing. It has good performance of anti-acid slag and anti-erosion, high refractoriness under load temperature. Mainly applied in the carbonization chamber, combustion chamber, walls of coke oven, roof and walls of glass furnace, high temperature load-bearing part of hot blast stove, carbon baking furnace and other thermal kilns.
