Silicon Carbide Production Process

Silicon Carbide | Washington Mills

The silicon carbide manufacturing process can be divided into two general steps: the production of SiC crude (generally, SiC lumps having a diameter of 3/8 inch or more) and the crushing and grading of the silicon carbide crude into finished sizes of grains and powders for sale to customers.

When silicon is heated it reacts with the halogens (fluorine, chlorine, bromine, and iodine) to form halides. It reacts with certain metals to form silicides and when heated in an electric furnace with carbon, a wear resistant ceramic called silicon carbide is produced. Hydrofluoric acid is the only acid that affects silicon.
