Silica Brick For Glass Kiln | light weight |silicon carbide |oxide bonded silicon carbide brick
Silica brick is mainly composed of scale quartz, cristobalite and a small amount of residual quartz and glass phase acid refractory material, with good acid slag erosion resistance. Is mainly used for coke oven of coking chamber and combustion chamber partition, steel-making furnace regenerator and sediment chamber, soaking furnace, glass furnace refractory and ceramic firing kiln kiln vault and other bearing parts.
