Silicon carbide is an artificially synthesized carbonized substance. It is generally formed at a high temperature of 2000 degrees Celsius when carbon and silicon dioxide are energized. Because silicon carbide has the advantages of high wear resistance, hard material, corrosion resistance and high high temperature strength, it is used in various wear-resistant, high-temperature resistant parts. Silicon carbide is a semiconductor at room temperature and has impurity conductivity properties. The higher the purity of silicon carbide, the resistivity will naturally decrease as the temperature gradually increases. Depending on the impurities contained in silicon carbide, the conductivity will be different, and 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, grinding blocks, and for grinding and polishing piezoelectric crystals in the electronics industry. Because silicon carbide is corrosion-resistant, high-temperature resistant, has good thermal conductivity, and has good impact resistance, it can be used as smelting furnace linings, silicon carbide plates, silicon carbide crucibles, lining plates, etc. At the same time, it can also be used as a high-temperature indirect heating material in the non-ferrous metal smelting industry;
Generally speaking, silicon carbide has many uses and can be widely used in different fields and plays an important role in different fields.
