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