优质碳化硅 SIC 97%含量

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, green silicon carbide and black silicon carbide is essentially the same, just different raw material and manufacturing process.

Green silicon carbide products are green and transparent, with a hardness and purity over black silicon carbide. It is suitable for grinding copper, brass, aluminum, gemstones, optical glass, ceramic and other hard alloy, metal and hard and brittle non-metallic materials. Its micropowder can also be used as a ceramic material. Most of it is used for hard alloy, titanium alloy and optical glass, and also for honing cylinder liner and grinding high speed steel cutter.

Black silicon carbide containing SiC by about 98%, based on quartz sand, petroleum coke and the high quality silica 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. Have metallic luster, its toughness is higher than the green silicon carbide, mostly used for processing low tensile strength of material, such as glass, ceramics, stone, refractory material, cast iron and nonferrous metal, etc., mainly used for grinding of cast iron and non-metallic materials.

1, abrasive - the main stability of silicon carbide with high hardness, toughness determined by silicon carbide can be used for manufacturing consolidation free abrasive, coated abrasive 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 oxygen carbon containing silicon slag for smelting steel cleaning agent is used for steelmaking deoxidizer cast iron as tissue conditioner 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

It is equipped with far-infrared radiation coating or silicon carbide silicon plate with far-infrared radiation dryer.

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.
