Description:

Black silicon carbide, also named black carborundum, is made of quality silicon sand (SiO2) and petroleum coke smelted in high temperature electric arc furnace. It is black crystal structure with high hardness, strong cutting ability, stable chemical characteristics and good thermal conductivity. Its hardness is higher than corundum, and ranks below diamond and its mechanical strength is higher than corundum.

Compared with green silicon carbide, its purity, hardness and brittleness are a little lower than green silicon carbide.

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:

Ceramic and glass, crystal and ferrite and nonmetal hard material lapping and polishing;

Optical resins materials, stone, agate and high-grade jewelry, refractory materials, castings and nonferrous metal processing;

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.
