Siliciumcarbide ( SiC ), ook bekend als carborundum, is een zeer hard materiaal dat veel wordt gebruikt voor slijpen en polijsten, in de vorm van slijpstenen, polijst- en slijppoeders en als bekleding van schuurpapier, en tegenwoordig ook voor de pantsering van pantservoertuigen. De verbinding is ontdekt door Edward. It occurs in nature as the extremely rare mineral moissanite. Silicon carbide , exceedingly har synthetically produced crystalline compound of silicon and carbon.
Its chemical formula is SiC. Since the late 19th century silicon carbide has been an important material for sandpapers, grinding wheels, and cutting tools. More recently, it has found application in refractory linings and . Learn the history of Silicon Carbide ( SiC ) including the variety of uses, pros and cons, and products produced using SiC. Silicon Carbide is a non oxide ceramic and is used in a wide range of products that must perform in thermally (high heat and heat shock) and mechanically demanding applications. Silicon has long been the semiconductor of choice for such power electronics.
But soon this ubiquitous substance will have to share the spotlight. Devices made from silicon carbide ( SiC )—a faster, tougher, and more efficient alternative to straight silicon—are beginning to take off. Formula and structure: The chemical formula of silicon carbide is SiC. Its molecular formula is CSi and its molar mass is 40. It is a simple compound with the carbon atom attached to silicon through a triple bon leaving both atoms with a positive and negative charge.
However, the bonding between them has a .

C OTHER INSULATING LAYERS ON SiC A variety of insulating layers, other than thermal oxide, have been deposited on SiC and are summarised in TABLE 2. It has been speculated that certain deposited insulators may prove to have better dielectric strength and longer useful lifetime at temperatures greater than 3°C.
