Silicon carbide with chemical formula of SiC, is one of the refractory materials, which as a raw material, will not be found in the nature. This material made artificially (Terms of synthesis). And are used in manufacturing of Refractory and abrasive products. These products are mainly used in the blast furnace, pickling machine, cathode copper vertical furnace, nozzles and furnaces to melt metals. Many of carbides are known. These compounds can be produced by heating the Respective metal with its acid or carbon, carbon monoxide or hydrocarbons. Silicon dissolves in almost all molten metals and many of these substances, certain compounds produced called silicide.
