High Temperature Performance and Thermal Shock Resistance Silicon-Mullite Brick
Description:
The silica brick is composed mainly of mullite, corundum, SiC and glass. It is formed at the junction of granules as mullite, glass and SiC.
Features:
01:the product structure is compact and good wear resistance.
02:high temperature and high temperature performance
03:lower the temperature of the kiln and good insulation performance.
Application:
It is widely used in steel, non-ferrous metal and chemical industries
