Coarse Silicon Carbide Grit

Black Silicon Carbide Particle Description

Abrasives Black silicon carbide is made from quartz sand and smokeless acetylene as the main raw material. It is made via light resistance from hydro metallurgical, it is black opaque body hexagonal crystal and MOHS-hardness the 9.15, which is after diamond and boron carbide with crisp and sharp performance and certain degree of conductive heat.

Black silicon carbide is higher toughness than green silicon carbide with sic purity 98%, it have been used for processing glass, ceramic, stone, refractory materials, cast iron and other metal.

Green silicon carbide is made of petroleum coke and silica as the main raw materials, adding salt as additives, and smelting at high temperature in a resistance furnace. It is green crystalline, brittle and sharp, and has certain thermal and electrical conductivity. The microscopic shape is hexagonal crystal, the Mohs hardness of silicon carbide is 9.3, the microdense hardness is 2940-3300kg/mm², and the hardness of Knoop is 2670-2815kg/mm³, which is higher than corundum in abrasives and second only to diamond, cubic boron nitride and boron carbide. The density is generally considered to be 3.20-3.25g/cm³.The natural bulk density of silicon carbide abrasive is between 1.2-1.6g/cm³, and the specific gravity is 3.20~3.25g/cm³.
