Silicon Carbide

About Silicon Carbide

Silicon carbide occurs naturally as the extremely rare mineral Moissanite, while most material is synthesised in factories. Due to its high hardness, it has been mass-produced as an abrasive since the late 19th century. When silicon carbide powder has a low level of purity, it exhibits a black colour. Products with a purity exceeding 90% appear green. Silicon carbide grains can be sintered to form ceramic materials. These ceramics serve as components in automotive braking systems or ballistic body armour. Silicon carbide parts operate at temperatures of 2 000 °C or above. Silicon carbide tubes are used in industrial furnaces and heat insulation devices, and in some turbine engines silicon carbide components replace metal parts.

Low-purity, inexpensive silicon carbide powder is used as an abrasive and as a component in cutting tools. High-purity products can be applied in the semiconductor industry.
