Silica Brick

Definition: Silica brick is made of high-quality silica as raw material, adding mineralizers and binders, etc., and firing after molding.
Silica brick series refractory brick：
1.Good thermal shock resistance
2.Strong glass corrosion resistance and high thermal shock stability.
3.Acid slag erosion resistance ability
4.High-purity raw material, barely no pollution.
5.Small change in reburning line
Application:
1. High quality silica brick are commonly used in crown, parapet, hanging wall and runner of glass kiln;
2. Ordinary silica brick is often used in coke oven bottom, furnace wall, combustion chamber and carbonization chamber partition wall and other parts;
3. Zero expansion silica brick is often used in glass kiln and coke oven hot repair.
4. Light weight silica brick is often used in the parapet insulation layer of the vault and melting part of glass kiln.
