Silicon carbide/Carborundum Introduction

Silicon Carbide (SiC) is an extremely hard (Mohs 9.1 / 2550 Knoop) man made mineral that possesses high thermal conductivity and high strength at elevated temperatures (at 1000°C, SiC is 7.5 times stronger than Al2O3). SiC has a modulus of elasticity of 410 GPa, with no decrease in strength up to 1600°C, and it does not melt at normal pressures but instead dissociates at 2600°C. At present, silicon carbide produced by Chinese industry is divided into black silicon carbide and green silicon carbide.We can provice different grade,from 50% to 98%.

 

Silicon Carbide Powder Feature

1.Good oxidation resistance and chemical stability at high temperatures.
2.High hardness with Mohs 9.2-9.3. Even at 2000ºC, it's still get high strength.
3.Excellent toughness.
4.Low thermal conductivity. So it can resistant to themal shock.
5.High purity min SiC content is 98.5%.
6.High bulk density.
7.Black silicon carbide grit is washed by water before milling process, so there is few impurities.

Other special spec. could be supplied as required.

Applications of black silicon carbide
 
Sliding parts (mechanical seals, bearings, shafts)
Crusher parts (classifier, airflow type crusher, beads mills)
Semiconductor manufacturing equipment parts (XY stages, MOCVD trays, focus rings, water chucks)
Molding machine parts (glass lens molding machine parts)
Heat resistant parts (burner nozzles, high temperature testing machine parts, metal melting crucibles)
Abrasion resistant parts (blast nozzles, shot blasting blades, buried pipe guard plates, fishing rod yarn paths)
