Silicon carbide - Wikipedia
Because natural moissanite is extremely scarce, most silicon carbide is synthetic. Silicon carbide is used as an abrasive, as well as a semiconductor and diamond simulant of gem quality. The simplest process to manufacture silicon carbide is to coine silica sand and carbon in an Acheson graphite electric resistance furnace at a high temperature, between 1,600 C (2,910 F) and 2,500 C (4,530 F).

Chemical industry | CGT Carbon
Carbon and graphite materials are resistant to chemical agents - no other traditional material has such a wide range of properties and appliions. The most important feature of carbon and graphite in this appliion is their resistance to almost all chemical compounds in a wide temperature range, except for strong oxidizing substances.

MERSEN | Purifiion and coatings
Purity constraints: Our purity processes allow us to achieve extremely low impurity levels, to below 5 ppm. The ETV-ICP method is used to detect and monitor impurities to levels below 5 ppb. Cleanliness constraints: Vitreous Carbon Impregnation (VCI) was developed to reduce particle emissions and the vacuum outgassing of materials, particularly for semi-conductor appliions.
