The appliion in metallurgical industry The hardness of silicon carbide is second only to diamond, which has strong wear resistance. It is the ideal material of mine bucket lining, wear resistant pipe, impeller, pump chaer and cyclone. Its wear resistance is 5
1. Introduction: Silicon Carbide is an extremely hard (Knoop 2600 or Mohs 9.4) man made mineral that possesses high thermal conductivity (100 W/m-K). It also has high strength at elevated temperatures (at 1000 C, Green SiC is 7.5 times stronger than Al2O3).
Silicon carbide (SiC) is almost as hard as a diamond, according to the Institute of Materials, Minerals, and Mining. It ranks a 9-9.5 on the Mohs hardness scale, slightly less than diamond, which What is best material selection for a Silie abrasive …
As we all know why the diamond grinding discs have not replaced silicon carbide paper. No matter the answers it boils down to, cross-contamination during sample preparations of samples. “Cross-contamination is the contamination of one sample by another sample that is being processed concurrently or that was processed prior to the current sample leaving a residue on the equipment being used.

The most common metallographic abrasive used is Silicon Carbide – SiC. It is an ideal abrasive for grinding because of its hardness and sharp edges. For metallographic preparation, SiC abrasives are used in coated abrasive grinding papers ranging from very coarse 60 grit to very fine 1200 grit sizes.
An important feature of both silicon carbide and diamond is that they exhibit piezoresistive properties. Hightemperature pressure sensors in silicon carbide substrates have been developed with stable operation up to about 500 C. Silicon carbide (SiC) has a nuer
