Product Description
Descriptions:
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.
Green Silicon Carbide is an extremely hard (Knoop 2600 or Mohs 9.4) man made mineral that possesses high thermal conductivity (100 W/m-K).
Green Silicon carbide also has high strength at elevated temperatures (at 1000°C, Green Silicon carbide is 7.5 times stronger than Al2O3).
Green Silicon carbide has a modulus of elasticity of 410 GPa, with no decrease in strength up to 1600°C;
Green Silicon carbide does not melt at normal pressures but instead dissociates at 2815.5°C.
Green Silicon carbide is an entirely new batch composition made from Silica sand and coke, and is extremely pure.
Green Silicon carbide can be manufactured in many complex bonded shapes, which are utilized for super refractory purposes.
Green Silicon carbide is also ideal for a wide variety of abrasive applications.
HIJO Abrasives offers a whole range of macro and micro grits in green silicon carbide, quality and various particle size distributions based on FEPA, and JIS standards.
