（GC) GREEN SILICON CARBIDE POWDER
Main particle size model:JIS240-JIS4000
F220-F1200
P220-P2500
W63-W3.5

Green silicon carbide is made of petroleum coke and high-quality silica as the main raw material, adding salt as an additive and smelting by electric furnace at high temperature. Its hardness is between corundum and diamond, and its mechanical strength is higher than that of corundum.
The green silicon carbide powder is green, crystal structure, high hardness, strong cutting ability, stable chemical properties and good thermal conductivity. The microscopic shape is hexagonal crystal, and the silicon carbide has a Mohs hardness of 9.2, which is higher than corundum in the abrasive and second only to diamond, cubic boron nitride and boron carbide. The density is generally considered to be 3.20 g/mm 3 , and the natural bulk density of the silicon carbide abrasive is between 1.2 and 1.6 g/mm 3 and the specific gravity is 3.20 to 3.25.

The main purpose:Green silicon carbide is mostly used for processing non-ferrous materials with high hardness and brittleness, such as cemented carbide and optical glass. It can also be used for polishing crystal and steel; precision polishing of ceramics and special steels; consolidation and coating of abrasives and cutting Free abrasive polishing, and can produce advanced refractory materials, factory ceramics, heating elements and thermal components. At the same time, according to market demand, it is specially used for cutting and grinding of solar wafers, semiconductor wafers and quartz stone chips.
