Green Silicon Carbide By Microgrand Abrasive Co., Ltd.

Our offered Green Silicon Carbide is produced from very high purity silica sand and petroleum coke. It is extremely hard (Knoop 2600 or Mohs 9.4), high thermal conductivity (100 W/m-K) and high strength at elevated temperatures (at 1000A C, Green SiC is 7.5 times stronger than Al2O3). Green SiC has a modulus of elasticity of 410 GPa, with no decrease in strength up to 1600A C, and it does not melt at normal pressures but instead dissociates at 2815.5A C. Being very hard and sharp makes it a very aggressive abrasive ideal for many applications where a higher purity is required.

Applications:
Green Silicon Carbide is the ideal abrasive for grinding / sanding materials of low tensile strength such as Cast Iron, Brass, Aluminum, Bronze etc. Its thermal properties make it an excellent medium for use in the manufacture of refractory products and crucibles. It is also used in marble and granite polishing, manufacture of Kin furniture and as a deoxidizer in Iron and steel making.
