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.
