Description of Silicon Carbide Brick:

Our factory supply high quality silicon carbide brick. Silicon carbide brick is a high-grade refractory made of SiC as the main raw material. It has a series of excellent properties, such as high strength at room temperature and high temperature, high thermal conductivity, small linear expansion coefficient, good thermal shock resistance, excellent high temperature abrasion resistance, strong chemical corrosion resistance, etc. It has been widely used in the fields of iron and steel, colored metallurgy, chemistry, electricity, ceramics, and aerospace.

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.

Features of of Silicon Carbide Brick:

1.High heat conductivity,
2.Good abrasive resistance,
3.Great thermal shock resistance,
4.Excellent erosion resisting,
5.Strong resistant to acid and alkali slag erosion,
6.High strength,
7.Low heat expansion coefficient.

Application of of Silicon Carbide Brick:

Silicon carbide refractory brick are widely used for aluminum tank liners, molten aluminum tube and ceramic kiln with kiln, the lower body and medium-sized blast furnace, furnace waist and belly stove, aluminum refining furnace lining, zinc distillation tank lining and so on.
