Silicon carbide (SiC) is a compound of silicon and carbon with the chemical formula SiC. Silicon carbide is a kind of carbide accidentally discovered in the laboratory by the American Acheson during the electromelting diamond experiment in 1891. It is made of quartz sand, petroleum coke (or coal coke), wood chips (salt is needed to produce green silicon carbide) and other raw materials by high temperature smelting through a resistance furnace. China’s industrial production of silicon carbide is divided into black silicon carbide and green silicon carbide.
Products: Black Silicon Carbide
SiC content is about 95%.
Advantage: High toughness
Application: Mostly used for processing materials with low tensile strength. Such as glass, ceramics, stone, refractory, cast iron and non-ferrous metals.
Application: Most of them are used for processing cemented carbide, titanium alloy and optical glass. Also used for fine grinding of high speed steel tools.

In industrial production, quartz, petroleum coke and so on are usually used as raw materials, in order to adjust the permeability of the charge and add an appropriate amount of wood chips. And then we put it all in an electric oven. Heat to about 2000°C. Silicon carbide powder was obtained by various chemical processes. Ps: An appropriate amount of salt should be added when preparing green silicon carbide.
