High purity green silicon carbide abrasive

Silicon carbide is made of quartz sand, petroleum coke (or coal coke), wood chips (salt is needed to produce green silicon carbide) and other raw materials are smelted at high temperature in a resistance furnace.

The hardness of the high-purity green silicon carbide abrasive is between corundum and diamond, and its mechanical strength is higher than that of corundum. It is very hard, brittle and sharp, has excellent thermal and electrical conductivity, and can resist oxidation at high temperatures.

Silicon carbide physical indicators:

 Silicon carbide is divided into black silicon carbide and green silicon carbide. The microscopic shape is hexagonal crystals. The Mohs hardness of silicon carbide is 9.5, and the Vickers micro-density hardness is 3000--3300 kg/mm. The general hardness is 2670-2815 kg/mm, and the micro hardness is 3300 kg per cubic millimeter. The density is generally considered to be 3.20 g/mm3, and the natural bulk density of the silicon carbide abrasive is between 1.2-1.6 g/mm3, and the specific gravity is 3.20～3.25.
