Silicon carbide is a high-performance ceramic material that can be used in thermal applications. It is also useful in mechanical and semiconductor applications. For example, silicon carbide is used in automotive brakes. In addition, it is used in the manufacturing of light-emitting diodes (LEDs).
Silicon carbide has a crystalline appearance, and the chemical formula is SiC. Silicon carbide has a high density and strength and is very resistant to thermal spalling. However, it is oxidizable and corrosive.
Silicon carbide can be produced in a variety of ways. In general, it can be formed as a bonded mass, or as a single crystal. During the production of a bonded mass, the powder is heated to a very high temperature in an electric furnace. This process produces a crystal with an iridescent black or green aggregate.
When used in a semiconductor, silicon carbide has a very high conductivity. It is also abrasion-resistant. This makes it a good choice for machining metals and abrasives.
Silicon carbide has been widely used in cutting tools for more than a century. Because of its high strength, it has been used to support and stabilize catalysts.
Silicon carbide has also been used to support a variety of abrasive machining processes. Acheson patented a method for producing silicon carbide powder on February 28, 1893.
Silicon carbide has been used in the production of abrasives, found crucibles, and lining work. Silicon carbide is used in diesel particulate filters, automotive brakes, and clutches.
