Black Silicon Carbide as a fuel and provide energy
Black Silicon Carbide /Black Carborundum is brittle and sharp.It is
produced at high temperature in electric resistance type furnace
with quarts sand and petroleum coke as its main raw materials. Its
hardness is between Aluminum Oxide and Synthetic Diamond.
Mechanical intensity of it is higher than Aluminum Oxide. It is
brittle and sharp and has electrical and heat conductivity in some
degree. It is suitable for make grinding wheels, cutting wheels,
mounted wheels, oil stone, abrasive media, and also suitable for
surface grinding, lapping or polishing. The abrasive products made
of it are suitable for working on Cast Iron, Non-ferrous Metal,
Rock, Leather, Rubber, Wood, ceramic, etc. It is also broadly used
as high-grade refractory material and metallurgical additive.

coefficient of linear expansion
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.
1, main silicon carbide abrasive, stability of high hardness,
toughness determined by sic grinding tool can be used in the
manufacture of consolidation, coated abrasive free grinding glass,
ceramics, stone, cast iron and some non-ferrous metals, hard alloy,
titanium alloy, high speed steel cutter grinding wheel, etc.
2, refractory corrosion resistant material - main silicon carbide
with high melting point (temperature), chemical inert reting
resistance silicon carbide can be used for abrasive, ceramic
products by burning kiln with shed board saggar, zinc smelting
industry vertical cylinder distillation furnace with carbon silica
brick, aluminum electrolytic cell line, crucible, such as a furnace
material of silicon carbide ceramic products.
3, chemical use, silicon carbide steel melt steel hydrolysis and
free oxygen, metal oxide reaction of carbon containing silicon
oxide slag for smelting steel cleaning agent is used for
steelmaking deoxidizer cast iron tissue conditioner, generally with
using low purity of silicon carbide to reduce the raw material for
manufacturing silicon tetrachloride.
4, electrical use, used for high temperature heating element,
nonlinear resistance element semiconductor material silicon carbide
heating element used in the 1100 ~ 1500 ℃ (furnace) nonlinear
resistance element all kinds of lightning protection valve plates.
5, the far-infrared radiation coating or silicon carbide silicon
dryer with far infrared radiation.
New silicon carbide products is widely used in a particular
industry, air conditioning, automotive engine, communications
equipment, radar stations, the missile defense system, the space
shuttle, and are used on aircraft carrier, especially in the aspect
of space, some special parts, silicon carbide products to be
reckoned with, and the effect of foreign resources, has the
advantages of domestic, therefore, the development of an
opportunity is also relatively well.
