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.
As the abrasive: used for abrasive, such as grinding wheels,
whetstone, grinding wheel, sand
As the metallurgical deoxidizer and high temperature material.
Four main application areas of SiC: functional ceramics, advanced
refractory, abrasives and
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.
a. More than twenty years of metallurgy technology and experience
in producing metallurgical burden in steelmaking, foundry, iron
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.
