Silicon Carbide

Silicon Carbide is a chemical compound that mainly consists of silicon and carbon. It is produced in an electrical resistance furnace from silica sand or quartz sand and petroleum coke at high temperatures. The function of industrial salt (NaCl) is to facilitate the removal of alumina and oxidized matter present in the material. Iron and other impurities.

Silicon Carbide is a chemical compound that mainly consists of silicon and carbon. It is produced in an electrical resistance furnace from silica sand or quartz sand and petroleum coke in high temperatures. The function of industrial salt (NaCl) is to facilitate the removal of alumina and oxidized matter present in the material. Iron and other impurities.


Pure silicon carbide is colorless and transparent, but due to the presence of free carbon, iron, silicon, and other impurities in industrially produced silicon carbide. The relative molecular mass of silicon carbide is 40.09, of which silicon accounts for 70.04% and carbon accounts for 29.964%. True density 3.21. Melting point (sublimation) 2600℃.


Silicon carbide has a high melting point, low specific gravity, Mohs hardness of 9.2, high strength, and good thermal shock stability. It is insoluble in water and acid but can be dissolved in molten alkali. Silicon carbide has poor oxidation resistance between 800 and 1140°C because the oxide film (SiO2) generated at this time is loose and cannot provide sufficient protection.
