Silica Brick

Silica brick is made of quartz containing more than 93% of silicon as the main raw material. It is a firebrick made by high temperature firing. It has strong corrosion resistance to acid slag, high softening degree under load, and does not shrink after refiring. It is mainly used for the partition wall of the carbonization chamber and the combustion chamber of the coke oven, the regenerator chamber of the steel furnace, the soaking furnace, the glass kiln and the ceramic firing kiln, and other supporting parts of the kiln. It is also used for high temperature bearing parts of hot blast furnaces and flat tops of acid furnaces.
