Black SiC-silicon carbide
Silicon Carbide is a kind of non-metallic carbide combined with silicon and carbon.
raw materials such as quartz sand, petroleum coke, wood chips, etc
it is smelted by an electric furnace at high temperature, with a hardness of 9.5.
Common silicon carbide is black or black-blue in appearance, which has the advantages of stable chemical properties, good wear resistance, and high thermal conductivity.
Since silicon carbide is a semiconductor, it has an anti-oxidation effect at high temperatures.
Industrial silicon carbide generally has a silicon carbide element content of 70 to 90% and contains a small amount of free carbon and other impurities.
