What is silicon carbide

Silicon carbide can also be called SiC. In terms of color, there are two kinds of black silicon carbide and green silicon carbide. According to the shape, there are silicon carbide blocks and silicon carbide powder.

Silicon carbide products manufacturing process:

The common method is to mix quartz sand with coke, use the silica and petroleum coke, add wood chips, put it into an electric furnace, heat it to a high temperature of about 2000 °C, and obtain silicon carbide after various chemical processes. To green silicon carbide, add salt.
