Silicon Carbide is the only chemical compound of carbon and silicon. It was originally produced by a high temperature electro-chemical reaction of sand and carbon. Silicon carbide is an excellent abrasive and has been produced and made into grinding wheels and other abrasive products for over one hundred years. Today the material has been developed into a high quality technical grade ceramic with very good mechanical properties. It is used in abrasives, refractories, ceramics, and numerous high-performance applications. The material can also be made an electrical conductor and has applications in resistance heating, flame igniters and electronic components. Structural and wear applications are constantly developing.It is produced from quartz sand and high quality anthracite under high temperature in an electric resistance furnace.If looks black and has a microhardness of 2800-3300kg\mm2,being used for produce the abrasive tools.It is also fit for process the grind metals and non-metals material of low tensile strength,such as grey cast iron,brass,aluminium ,stone,leather and hard rubber ect.Also can be used as refractory materials and in electronic industry.
