Product Description
Because of the rarity of natural moissanite, most silicon carbide is synthetic. It is used as an abrasive, and more recently as a semiconductor and diamond simulant of gem quality. The simplest manufacturing process is to combine 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). Fine SiO2 particles in plant material (e.g. rice husks) can be converted to SiC by heating in the excess carbon from the organic material. The silica fume, which is a byproduct of producing silicon metal and ferrosilicon alloys, also can be converted to SiC by heating with graphite at 1,500 °C (2,730 °F).
Advantages of black silicon carbide
1. Corrosion resistance, high strength, high hardness.
2. Good wear-resisting performance,resist to shock.
3. It is a cost-effective substitute for Ferrosilicon.
4. It has Multi-functions.
A: Remove oxygen from iron compound.
B: Adjust the carbon content.
C: Act as a fuel and provide energy.
5. It costs less than ferrosilicon and carbon combination.
6. It has no dust nuisance while feeding the material.
7. It can speed up the reaction.

Packaging & Shipping
Black silicon carbide is produced at high temperature in an electric resistance type furnace with quartz sand and petroleum coke as its main raw materials. Its hardness is between fused alumina and synthetic diamond. Mechanical intensity of it is higher than fused alumina. It is brittle and sharp and sharp and heat conductivity in some degree. The abrasive made of it are suitable for working on cast iron, non-ferrous metal, rock, leather, rubber, etc It is also broadly used as refractory material and metallurgical additive.
