Black silicon carbide is quartz sand and petroleum coke as the main
raw material, through high temperature electric resistance furnace
smelting, its hardness is between fused alumina and between diamond
and mechanical strength higher than that of corundum, sharp and
crisp. Has a certain electrical conductivity and thermal
conductivity.Made grinding tool, its use in processing low tensile
strength of metal and nonmetal materials.Such as gray cast iron,
non-ferrous metal, stone, leather, rubber, etc. Also widely used in
refractory material and metallurgical additive.Particle size can be
processed according to customer's requirements, 30-90 content of
various indicators of silicon carbide for you to choose, packing
tons of packaging, packaging size can be adjusted according to your
requirements, can be provided free of charge a small amount of
samples for testing.
Features of Black Silicon Carbide
◆ Light weight and high hardness (Moh's hardness:9.2);
◆ Super deoxidizing agent;
◆ Stable chemical characteristics(very low chemical activity)；
◆ Excellent performance of thermal conductivity;
◆ Small thermal expansion coefficient;
◆ Super performance of wear-resisting;
◆ High oxidation resistance under high temperature.
Second grade black silicon carbide (SiC85%) mainly used in
steelmaking as super deoxidizing agent to speed it up,easy to
control steel chemical component and improve the steel quality ;
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.
