Product Details


Description of Silicon Nitride Silicon Carbide Brick


The Si3N4 SiC blocks are widely used as lining bricks of large aluminum electrolytic cell. Using nitride bonded silicon carbide products enlarges the tank capacity, improves the thermal conductivity, enables rapid cooling, and increases the tank production capacity at the same time. Alumina and cryolite of eutectic content can form on bricks' surface, which can protect the tank lining work layer, and prolong the tank's service life. 


Therefore, silicon nitride bonded silicon carbide bricks are widely used in the aluminum industry.
