Silicon carbide is a hard chemical compound containing silicon and carbon. It is a semiconductor that can be doped n-type by nitrogen or phosphorus and p-type by beryllium, boron, aluminium, or gallium. Metallic conductivity has been achieved by heavy doping with boron, aluminium or nitrogen. Silicon carbide is used in a wide range of industries due to its versatile properties. It provides benefits for high-temperature, high-voltage, and high-power applications. Some of its features include great mechanical strength, high-temperature resistance, chemical inertness, and variable electrical conductivity. Silicon carbide is used in manufacturing for its hardness in abrasive machining processes such as grinding, honing, water-jet cutting, and sandblasting. It is also used as a raw ingredient in some glazes applied to ceramics. Silicon carbide is an important material in TRISO-coated fuel particles, the type of nuclear fuel found in high-temperature gas-cooled reactors such as the Pebble Bed Reactor. Silicon carbide is also used to manufacture bulletproof armor due to its hardness. Electric vehicles powered by silicon carbide are highly efficient and cost-effective.
