2. Related introduction
Silicon carbide has four main application areas, namely: functional ceramics, advanced refractory materials, abrasives, and metallurgical raw materials. Silicon carbide is available in large quantities and cannot be considered a high-tech product, while the application of nanoscale silicon carbide powder, which has a very high technical content, is unlikely to form an economy of scale in a short period.
(1) As abrasives, they can be used for abrasives, such as grinding wheels, oil stones, grinding heads, tiles, etc.
(2) As metallurgical deoxidizer and high-temperature resistant material.
(3) High purity single crystal, which can be used for manufacturing semiconductors and making silicon carbide fiber.
Main uses: for 3-12 inch single crystal silicon, polycrystalline silicon, potassium arsenide, quartz crystal, and other wire cutting. Solar photovoltaic industry, semiconductor industry, piezoelectric crystal industry engineering processing materials.
Used in semiconductors, lightning rods, circuit components, high-temperature applications, UV detectors, structural materials, astronomy, disc brakes, clutches, diesel particulate filters, fine filament pyrometers, ceramic films, cutting tools, heating elements, nuclear fuel, jewelry, steel, protective gear, catalytic stretcher, etc.
1. Abrasives
Mainly used for making grinding wheels, sandpaper, abrasive belts, oil stones, grinding blocks, grinding heads, abrasive pastes, and grinding and polishing of monocrystalline silicon, polycrystalline silicon in photovoltaic products and piezoelectric crystals in the electronics industry, etc.
2. Chemical
It can be used as a deoxidizer for steel making and a modifier for cast iron organization and can be used as a raw material for manufacturing silicon tetrachloride, which is the main raw material for the silicone resin industry. Silicon carbide deoxidizer is a new type of strong composite deoxidizer, replacing the traditional silicon powder toner for deoxidation, and the original process compared to the physical and chemical properties are more stable, good deoxidation effect, so that the deoxidation time is shortened, saving energy, improve the efficiency of steelmaking, improve the quality of steel, reduce the consumption of raw and auxiliary materials, reduce environmental pollution, improve labor conditions, improve the overall economic benefits of the electric furnace are of great value.
3. "Three resistant" materials
The use of silicon carbide has corrosion resistance, high-temperature resistance, high strength, good thermal conductivity, impact resistance, and other characteristics, silicon carbide on the one hand can be used for a variety of smelting furnace lining, high-temperature kiln components, silicon carbide plate, liner, support parts, sagger, silicon carbide crucible, 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 furnace, distillation furnace tower plate, aluminum electrolytic tank, copper melting furnace lining, zinc powder furnace with arc plate, thermocouple protection tube, etc.; it is used to make wear-resistant, corrosion-resistant, high temperature resistant and other advanced silicon carbide ceramic materials; it can also be made into rocket nozzle, gas turbine blades, etc. In addition, silicon carbide is also one of the ideal materials for highways, aerospace runways solar water heaters, etc.
4. Non-ferrous metals
The use of silicon carbide has high-temperature resistance, high strength, good thermal conductivity, impact resistance, for high-temperature indirect heating materials, such as the firm tank distillation furnace, distillation furnace tower plate, aluminum electrolytic tank, copper melting furnace lining, zinc powder furnace with arc plate, thermocouple protection tube, etc.
5. Steel
Using the corrosion resistance of silicon carbide, resistance to thermal shock and abrasion, and good thermal conductivity, it is used in the lining of large blast furnaces to improve the service life.
6. Metallurgy and mineral processing
Silicon carbide is second only to diamond in hardness and has strong wear resistance, which is ideal for lining wear-resistant pipes, impellers, pump chambers, cyclones, and hoppers. The rubber service life of 5-20 times is also one of the ideal materials for the aviation runway.
7. Building materials ceramic grinding wheel industry
The use of its thermal conductivity, thermal radiation, the high thermal intensity of the characteristics of the manufacture of thin plate kiln furniture, not only to reduce the capacity of the kiln but also to improve the installed capacity of the kiln and product quality, shorten the production cycle, is the ideal indirect material for ceramic glaze baking sintering.
8. Energy saving
Using good thermal conductivity and thermal stability, as a heat exchanger, the combustion consumption is reduced by 20%, saving fuel by 35%, making the productivity increase by 20-30%, especially the internal release of the emission conveying pipe used in the mine selection plant, its wear resistance is 6-7 times that of ordinary wear-resistant materials.
Abrasive particle size and its composition according to GB/T2477--83. Abrasive particle size composition determination method according to GB/T2481--83.
9. Jewelry
Synthetic Moissanite (Synthetic Moissanite), also known as synthetic moissanite, synthetic carbon silica (chemical composition SiC), dispersion 0.104, larger than the diamond (0.044), refractive index 2.65-2.69 (diamond 2.42), with the same diamond diamond diamond diamond luster, "fire color " is stronger and closer to diamond than any previous imitation.
10. Sandblasting to remove rust.
The product is made of brown corundum micro powder extruded by high pressure, high-temperature sintering molding, moderate hardness, clean and clean, not easy to break. The product can be used repeatedly and many times, with a good sandblasting effect.
