Description:

Black silicon carbide is produced at high temperature in an electric resistance type furnace with

 quarts 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 sharp and

has electrical and heat conductivity in some degree.

Features of Black Silicon Carbide

Stable chemical characteristics(very low chemical activity)

Excellent performance of thermal conductivity;

Small thermal expansion coefficient;

Super performance of wear-resisting;

Light weight and high hardness (Moh's hardness:9.2);

Super deoxidizing agent;

High oxidation resistance under high temperature.

Application range:

As the abrasive: used for abrasive, such as grinding wheels, whetstone, grinding wheel, sand

 tiles etc.

As the metallurgical deoxidizer and high temperature material.

Four main application areas of SiC: functional ceramics, advanced refractory, abrasives and

 metallurgical materials.

High purity single crystal, used to manufacture semiconductors, manufacture of silicon carbide fibers.

Silicon carbide is very hard, with excellent thermal conductivity, as a semiconductor and high

temperature resistant to oxidation.

Competitive advantage:

a. More than twenty years of metallurgy technology and experience in producing metallurgical burden in steelmaking, foundry, iron casting etc.

b. More professional technicians, strict raw materials choosing and accurate matching principle in metallurgy, proper furnace temperature control, advanced processing and testing equipment make sure the stable good quality of products.

c. More competitive price due to cheaper electric power charge since our factory located in Northwest of China, sharing the favorable power charge.

d. Professional international trade specialists provide you a considerate and easy procurement.
