Silica carbide brick is a kind of refractory product mainly made of SiC, the silica carbide content is 72%~99%. Generally, the black silica carbide( content above 96%), add binding agent(or non-binding agent), made by the burdening, mixing, molding and burnt. The principal crystalline phase is SiC.
It can be used for lining of aluminum electrolyzers, molten aluminum ducts and kilns for ceramic kilns, lower parts of large and medium-sized blast furnace shafts, hearths and hearths, aluminum refining furnace linings, zinc distillation tank linings, etc.
