Silicon carbide is a synthetic carbide substance, generally formed at a high temperature of 2000 degrees Celsius, carbon and silicon dioxide after electricity is applied. Because silicon carbide has the advantages of wear resistance, hard material, corrosion resistance and high temperature strength, it is used in various parts that work such as wear resistance and high temperature resistance. Silicon carbide is a semiconductor at room temperature and has impurity conductivity. The higher the purity of silicon carbide, the higher the resistivity naturally decreases as the temperature gradually increases. According to the difference in the impurities contained in the silicon carbide, the conductivity is also different, and the silicon carbide has good hydrophilicity and far-infrared radiation.

Silicon carbide can be used in abrasive tools, as an ingredient to make grinding wheels, sandpaper, abrasive blocks and piezoelectric crystals in the electronics industry for grinding and polishing. Because of its corrosion resistance, high temperature resistance, good thermal conductivity and good impact resistance, silicon carbide can be used as smelting furnace lining, silicon carbide plate, silicon carbide crucible, lining plate, etc. At the same time, it can also be used as a high-temperature indirect heating material in the non-ferrous metal smelting industry.

In general, silicon carbide has many uses, can be widely used in different fields, and plays a role in different fields.
