Performance and Features

Silicon carbide, due to its stable chemical properties, high thermal conductivity, small thermal expansion coefficient, and good wear resistance, in addition to abrasives, has many other uses, such as silicon carbide powder coated on the inner wall of the turbine impeller or cylinder block by a special process, which can improve its wear resistance and extend the service life by 1~2 times; The high-grade refractory materials used to make them are resistant to thermal shock, small in size, light in weight and high in strength, and have good energy-saving effects. Low-grade silicon carbide (containing about 85% SiC) is an excellent oxygen absorber, speeding up steelmaking and facilitating chemical composition control to improve steel quality. In addition, silicon carbide is also widely used in the production of silicon carbon rods, and electric heating elements.

Application

Silicon carbide is used in various fields, such as:

(1) In the building materials ceramic grinding wheel industry, the use of its thermal conductivity, thermal radiation, and high thermal strength characteristics, the manufacture of thin plate kiln furniture, not only can reduce the capacity of the kiln, but also improve the kiln capacity and product quality, shorten the production cycle, is the ceramic glaze baking sintering ideal indirect material.

(2) In metallurgical beneficiation, silicon carbide hardness is second only to diamond, with strong wear resistance, is an ideal material for wear-resistant pipes, impellers, pump chambers, cyclones, and mine hopper linings, and its wear resistance is cast iron. Rubber has a service life of 5-20 times and is also one of the ideal materials for aviation flight runways.

(3) In terms of "three resistance" material, silicon carbide has the characteristics of corrosion resistance, high-temperature resistance, high strength, good thermal conductivity, etc. so it can be used for various smelting furnace linings, high-temperature furnace components, silicon carbide plates, silicon carbide crucibles, etc., on the other hand, it can be used for high-temperature indirect heating materials in the non-ferrous metal smelting industry, such as vertical tank distillation furnaces, rectification furnace trays, aluminum electrolytic cells, etc., and can also be used to make high-grade silicon carbide ceramic materials such as wear resistance, corrosion resistance, and high-temperature resistance; It can also be made into rocket nozzles, gas turbine blades, etc. In addition, silicon carbide is also one of the ideal materials for highways, aviation airstrips, solar water heaters, etc.

(4) In the chemical industry, it can be used as a deoxidizer for steelmaking and a modifier for cast iron structure and can be used as a raw material for the manufacture of silicon tetrachloride, which is the main raw material of the silicone resin industry. Silicon carbide deoxidizer is a new type of strong composite deoxidizer, replacing the traditional silicon powder for deoxidation, compared with the original process, the physical and chemical properties are more stable, the deoxidation effect is good, so the deoxygenation time is shortened, energy saving, improve steelmaking efficiency, improve the quality of steel, reduce the consumption of raw and auxiliary materials, reduce environmental pollution, improve working conditions, and improve the comprehensive economic benefits of electric furnaces have important value.

Not only these, but silicon carbide also has many other uses, so it is widely used in many industries.
