Silicon carbide(SIC) is mainly made of quartz sand and petroleum coke as the raw material under high temperature electric resistance furnace smelting. Its hardness is between fused alumina and diamond and mechanical strength higher than that of corundum, it’s sharp and crisp which has electrical conductivity and thermal conductivity. With the production of abrasive,which is suitable for processing low tensile strength of metal and nonmetal materials. Such as grey cast iron, non-ferrous metal, stone, leather, rubber, etc. It is also widely used in refractory, metallurgical additives, mainly used for refractory materials. Product manufacturing, foam ceramic industry, solar silicon cutting, crystal cutting, grinding, original car engine manufacturing, coating industry, plastics modification, desulfurization, power supply, environmental protection industry, etc.
Different forms of silicon carbide will have different applications, its application is very extensive, just take a look at the below the scope of application of several major categories.

　　
Abrasives
It is mainly used for grinding wheel, abrasive paper, abrasive belt, abrasive, grinding, grinding head, grinding paste and monocrystalline silicon, polycrystalline silicon photovoltaic products and electronic industry of piezoelectric crystal aspects such as grinding, polishing, etc.

Chemical Industry
It can be used as the steelmaking deoxidizer and cast iron modifier, can be used as raw material of manufacture of silicon tetrachloride, which is the main raw material of silicone industry.Silicon carbide deoxidizer is a new kind of compound deoxidizer, which replaced the traditional solid silicon powder carbon powder. Compared with the original process,it’s various physical and chemical performance is more stable, deoxidization effect is better, deoxidize shorter time, save energy and improve the efficiency of steel. It also improve the quality of steel, reduce raw material consumption and environmental pollution, improve working conditions and which has important value on improving the benefit of electric furnace comprehensive economic.

Three Resistant Material
Because of silicon carbide has corrosion resistance, high temperature resistance, strength, good thermal conductivity and impact resistance and other properties. On the one hand, silicon carbide can be used for all kinds of smelting furnace lining, high temperature furnaces artifacts, silicon carbide plate, plate, supports, sagger, silicon carbide crucible, etc
On the other hand, it can be used in high-temperature indirect heating of non-ferrous metal smelting industry, such as vertical distillation furnace, furnace distillation tray, aluminium electrolyzer, copper melting furnace lining, furnace zinc powder with arc plate, the thermocouple protection tube, etc. It also can be used to produce wear-resisting, corrosion resistant, high temperature resistance and other advanced silicon carbide ceramic materials. It can also make the rocket nozzle, gas turbine blades, etc.In addition, silicon carbide is one of the ideal material of highway, aviation airport runway solar water heater, etc.

Non-ferrous metal
As silicon carbide has high temperature resistance, strength, good thermal performance, impact resistant and high temperature for indirect heating materials. Such as strong retort furnace, tray distillation furnace, aluminium electrolyzer, copper melting furnace lining, furnace zinc powder with arc plate and the thermocouple protection tube, etc.

Steel Industry
Using these good characteristics of silicon carbide corrosion resistance, thermal shock resistance to wear and thermal conductivity, improves the service life for large blast furnace lining.

Metallurgical
Silicon carbide hardness is second only to diamond with strong wear resistance. It’s ideal material of wear-resisting pipe, the impeller, pump room, cyclone and pipe lined. It’s wear resistance is 5 -- 20 times the service life of cast iron and rubber, and def aviation flight track is one of the ideal material.

Vitrified Grinding Wheel Industry
Using the characteristics of the coefficient of thermal conductivity, thermal radiation, high strength, it can produce sheet kiln furniture. It not only can reduce the capacity of kiln furniture, also improve the loading capacity of the kiln and the product quality, shorten the production cycle, which is the indirect materials of the ideal of ceramic glaze baking sintering .

Energy Saving
With good thermal conductivity and thermal stability, it can be used as heat exchanger.And burnup decreased by 20% and saving fuel by 35% so that improve productivity by 20-30% especially at mill plant with the discharge pipeline, the wear-resisting degree of wear resistant material is 6 -- 7 times the ordinary resistant material.

Jewelry
Synthesis of silicon carbide (Synthetic Moissanite) also known as Synthetic mo SangShi, (SiC), the refractive index is the same as the diamond adamantine luster, color "fire"stronger than any previous imitation and more closer to the diamonds.This is produced by the north Carolina C3 manufacturing company which has the world's patent and widely applied to the world.
