Brief introduction of green silicon carbide
Green Silicon Carbide abrasives 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 superrefractory purposes.
Green Silicon carbide is also ideal for a wide variety of abrasive applications.
