Silicon carbide - Knowino
Silicon carbide (SiC) is a mineral which occurs extremely rarely in nature. When it does it is referred to as moissanite.It is probably most commonly known for its use as an abrasive due to the extreme hardness of the material, which is only exceeded by the
Silicon carbide | DeepRad
The silicon reacts with the graphite in the carbon-carbon composite to become carbon-fiber-reinforced silicon carbide (C/SiC). These discs are used on some road-going sports cars, supercars, as well as other performance cars including the Porsche Carrera GT, the Bugatti Veyron, the Chevrolet Corvette ZR1, the McLaren P1, Bentley, Ferrari, Laorghini and some specific high-performance Audi cars.
silicon carbide fibres
The second method of producing silicon carbide fibres is based on pyrolysis of polycarbosilane filaments. The resulting fibres contain carbon and oxygen in addition to nanocrystalline silicon carbide; improvements in production of this type of fibres is aimed at reducing the content of those elements, which is accompanied by an enhancement of their mechanical characteristics.
