History

Because natural moissanite is extremely scarce, most silicon carbide is synthetic. Silicon carbide is used as an abrasive, as well as a semiconductor and diamond simulant of gem quality. The simplest process to manufacture silicon carbide is to coine silica sand and carbon in an Acheson graphite electric resistance furnace at a high temperature, between 1,600 C (2,910 F) and 2,500 C (4,530 F).

Silicon Carbide | Ceramic | Sintered | SiC

Silicon carbide ceramics have excellent wear resistance and are widely used as mechanical seals. The corrosion resistance ensures wide use in the Chemical Industry. ISN offer 2 grades of silicon carbide, Sycarb 10 , a sintered silicon carbide and Sycarb 20 , a reaction bonded grade.
