Product Description

We can supply quality Black Silicon Carbide grains and micro powder based on ISO standard, FEPA standard, P standard for coated abrasives & JIS standard.


Silicon carbide (SiC) is using quartz sand and petroleum coke or coal tar, wood chips as raw material through high temperature electric resistance furnace smelting.There is also a rare mineral silicon carbide in nature, and the mo SangShi.Silicon carbide is also called the moissanite.In contemporary C, N, B the oxide refractory raw materials in the high technology, such as silicon carbide as the most widely used, one of the most economic.Can be called corundum sand or refractory.At present, the industrial production of silicon carbide can be divided into two black silicon carbide and green silicon carbide, are the six-party crystal, specific gravity of 3.20 ~ 3.25, the microhardness of 2840 ~ 3320 kg/was.


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.

Silicon carbide usage:

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.
