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/mm2, 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.

Application
It is mainly used for grinding and polishing of grinding wheels, sandpaper, abrasive belts, oil stones, grinding blocks, grinding heads, grinding pastes and monocrystalline silicon, polysilicon and piezoelectric crystals in the electronics industry in photovoltaic products.
It can be used for high temperature indirect heating materials in the non-ferrous metal smelting industry, such as vertical tank distillation furnace, rectification furnace tray, aluminum electrolytic cell, copper melting furnace lining, zinc powder furnace arc plate, thermocouple protection tube.
Using its thermal conductivity, heat radiation, high thermal strength characteristics, the manufacture of thin plate kiln furniture, not only can reduce the capacity of kiln furniture, but also improve the kiln capacity and product quality, shorten the production cycle, is the ceramic glaze baking and sintering ideal indirect material.
