Silicon carbide hardness is very large, Mohs hardness of 9.5, second only to the world's hardest diamond (10), has excellent thermal conductivity, is a kind of semiconductor, high temperature can resist oxidation.
Use of silicon carbide:
Silicon carbide has four main application areas, namely: functional ceramics, advanced refractory materials, abrasives and metallurgical raw materials. The coarse silicon carbide material can be supplied in large quantities, can not be counted as high-tech products, and the application of nano-level silicon carbide powder and high purity silicon carbide powder with very high technology content is short, high technology content, with the development of the third generation of semiconductors, silicon carbide will become the darling of the market.
My company production of silicon carbide development direction is high-grade silicon carbide abrasive. Used for a variety of materials of high precision processing and mirror polishing, such as: plastic fiber polishing, ceramic fiber degluing rough grinding, floppy disk head fine grinding polishing, jade, gems, crystal, ceramics, precision glass grinding, polishing, and electronic industry of piezoelectric crystal grinding, polishing, etc.
