The use of silicon carbide
May 21, 2018

1. The use of abrasives

It is mainly used for grinding, polishing and other aspects of grinding of single-crystal silicon, polysilicon, and piezoelectric crystals in the electronics industry for grinding wheels, abrasive belts, oil stones, grinding blocks, grinding heads, grinding pastes, and photovoltaic products.


2. Chemical use

It can be used as a deoxidizer for steelmaking and as a modifier for cast iron structures. It can be used as a raw material for the manufacture of silicon tetrachloride and is the main raw material for the silicone industry. Silicon carbide deoxidizer is a new type of strong composite deoxidizer which replaces the traditional silicon powder and carbon powder for deoxidation. Compared with the original technology, the physical and chemical properties are more stable, the deoxidation effect is good, the deoxidation time is shortened, and energy conservation is improved. Steelmaking efficiency, improving the quality of steel, reducing the consumption of raw and auxiliary materials, reducing environmental pollution, improving working conditions, and improving the overall economic efficiency of electric furnaces are of great value.

3. For wear-resistant, fire-resistant and corrosion-resistant materials

The use of silicon carbide has the characteristics of corrosion resistance, high temperature resistance, high strength, good thermal conductivity, and impact resistance. Silicon carbide can be used on various smelting furnace linings, high-temperature furnace construction, silicon carbide plates, liners, bearings, and crucibles, etc.; on the other hand it can be used for high temperature non-ferrous metal smelting industry Introduction heating materials such as vertical distillation tank, distillation tower tray, aluminum electrolytic tank, copper melting furnace lining, zinc powder furnace arc plate, thermocouple protection tubes, etc.; for the production of wear-resistant, corrosion-resistant, high temperature and other advanced silicon carbide ceramic materials; can also make rocket nozzles, gas turbine blades and so on. In addition, silicon carbide is also an ideal material for highways and airline runways.
