Silicon carbide – 270 W/m•K. Silicon carbide is a semiconductor that is composed of a balanced mixture of silicon and carbon atoms. When manufactured and fused together, silicon and carbon bind to form an extremely hard and durable material. This mixture is often used as a component for car brakes, turbine machines and in steel mixtures.

Basic Parameters of Silicon Carbide (SiC)

Silicon carbide crystallizes in numerous (more than 200 ) different modifiions (polylypes). The most important are: cubic unit cell: 3C-SiC (cubic unit cell, zincblende); 2H-SiC; 4H-SiC; 6H-SiC (hexagonal unit cell, wurtzile ); 15R-SiC (rhoohedral unit cell).Other polylypes with rhornbohedral unit cell: 21R-SiC 24R-SiC, 27R-SiC etc.

How silicon is made - material, making, history, used

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.
