Silicon Carbide (SiC) Properties and Appliions

Silicon carbide (SiC) is a hard covalently bonded material predominantly produced by the carbothermal reduction of silica (typically using the Acheson process). Depending on the exact reaction conditions the resulting silicon carbide is either a fine powder or a bonded mass that requires crushing and milling to produce a usable feedstock.
