99% SiC Green Silicon Carbide F8-F220 JIS 280#-10000# 63C 64C
Green Silicon Carbide grains 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 grainsalso has high strength at elevated temperatures (at 1000°C,Green Silicon carbide grainsis 7.5 times stronger than Al2O3).
Green Silicon carbide grainshas a modulus of elasticity of 410 GPa, with no decrease in strength up to 1600°C;
Green Silicon carbide grainsdoes not melt at normal pressures but instead dissociates at 2815.5°C.
Green Silicon carbide grainsis an entirely new batch composition made from Silica sand and coke, and is extremely pure.
Green Silicon carbide grainscan be manufactured in many complex bonded shapes, which are utilized for superrefractory purposes.
Green Silicon carbide grainsis also ideal for a wide variety of abrasive applications.
