Is Silicon Carbide a Good Conductor of Electricity
Silicon carbide is an extremely hard bluish-black insoluble crystalline substanceproduced by heating carbon with sand at a high temperature andused as an abrasive and refractory material. There are many appliions of silicon carbide, such as slide bearings, sealing rings, wear parts, sintering aids, crucibles, semiconductor appliions, heating elements, burner nozzles, heat exchangers.
Silicon carbide powder is used as an abrasive for such as grinding wheels, whetstone, grinding wheel and sand tiles. Silicon carbide is used to produce epitaxial grapheme by graphitization at high temperatures. It is also acts asthe metallurgical deoxidizer material.
Silicon nitride bearing balls have a coefficient of thermal expansion just 25% if most steel balls, so there is less friction generated in the bearing as heat increases. The low thermal conductivity of silicon nitride balls reduces the amount of heat absorbed, thus reducing cooling system requirements.

Alternatively, silicon nitride or elemental silicon may be doped with a nuer of doping elements, e.g., hydrogen, to form materials which are more easily etched by fluoride based etches. The methods are particularly useful for pre-cleaning contact vias residing in a layer of silicon oxide based material because they minimize the unwanted increase of critical dimension of contact vias.
