It has strong corrosion resistance to acidic slag and has a high load softening temperature. Silica bricks will undergo irreversible volume expansion when heated below 600°C, which will make the joints close and ensure good air tightness and structural strength of the masonry.

Description
Silicon bricks are a refractory product with silicon dioxide as the main component and its content is more than 94%. The higher the SiO2 content of the silica raw material, the higher the refractoriness. It belongs to acid refractory material, so it has strong resistance to acid slag erosion and has higher softening temperature under load.

Application
1. The silicon bricks are mainly used in the partition wall of the carbonization chamber and combustion chamber of the coke oven, the regenerator chamber and sediment chamber of the open hearth furnace of the steel making , the average heating furnace, the refractory material of the glass melting kiln and the kiln of the ceramic, and other bearing parts of the kiln.
