Product Name:SIC Silicon Carbide Ceramics

Chemshun Ceramics SIC Classification :

 Chemshun Ceramics Company can supply industrial silicon carbide products, no matter pressureless sintering ceramics (SSIC) or reaction sintering ceramics (SISIC). SSIC and SISIC is difference in firing process. So pressureless sintering ceramics have different technical parameters & product performance with reaction sintering ceramics.


 Silicon Carbide Introduction :

 Silicon Carbide was originally produced by a high temperature electro-chemical reaction of sand and carbon. Silicon carbide is an excellent abrasive and made into grinding wheels and other abrasive products. 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 a large number of high-performance applications. Silicon Carbide can also be made an electrical conductor and has applications in resistance heating, flame ignite and electronic components.
