Black Silicon Carbide Introduction

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).

Black silicon carbide is a high-quality abrasive material made from silicon carbide grains and petroleum coke in an electric resistance furnace at high temperatures. It is one of the hardest synthetic abrasives available and is known for its exceptional hardness, high thermal conductivity, and low thermal expansion coefficient.
Black silicon carbide has a black color and its unique crystal structure makes it highly resistant to wear and tear, chemical corrosion, and thermal shock. It is widely used in the manufacturing of grinding wheels, cutting tools, and abrasive blasting media.

Black silicon carbide is also used in various industrial applications such as surface preparation, metalworking, and ceramics manufacturing. Its properties make it an excellent choice for use in high-temperature applications, such as furnace linings, refractories, and heating elements.

Overall, black silicon carbide is a versatile and highly effective abrasive material that offers exceptional performance and durability in a range of applications, making it a popular choice among manufacturers and industrial users.

Our Advantages

 

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. 

Application
Grinding wheels made of C are suitable forthe grinding of metal and nometalic materialsof low tensile strength such as grey cast iron,brass,aluminium,stone materials. leather and rubber etc. Moreover, it can also beused in the manufacture of refractory prod.ucts and electric products etc.

 

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.
