Andalusite SiC Silicon Carbon Refractory Brick
The Description:
Silicon carbide brick is a refractory material made of SiC as the main raw material. Mohs hardness 9. More stable for acidic slag. SiC 72% ~ 99%. It is divided into clay bonded, Si3N4 bonded, Sialon bonded, β-SiC bonded, Si2ON2 bonded and recrystallized silicon carbide bricks. Mainly used for non-ferrous metallurgy retort, casting aluminum mold, electric furnace lining and heat exchanger.
