Silicon carbide brick types

Silicon carbide bricks can be divided into oxide bonding (clay bonding, mullite bonding, SiO2 bonding), nitride bonding (Si3N4 bonding, Sialon bonding), and self-bonding according to the bonding mode( β- SiC bonded and recrystallized silicon carbide) and siliconized reaction sintered silicon carbide bricks.

high-quality silicon carbide refractory brick manufacturer

Silicon carbide bricks are refractory materials made of SiC as the main raw material. Containing SiC72%~99%. It is divided into clay-bonded, Si3N4 bonded, Sialon bonded, β-SiC bonded, Si2ON2 bonded, and recrystallized silicon carbide bricks. Silicon carbide bricks have high thermal conductivity and good wear resistance, thermal shock resistance, and corrosion resistance. It can be used for aluminum electrolytic cell linings, molten aluminum conduits and kiln furniture for ceramic kilns, lower parts of large and medium-sized blast furnaces, waists and belly, aluminum refining furnace linings, zinc distillation tank linings, etc.
