Black Silicon Carbide

Description of Black Silicon Carbide

Black silicon carbide is made of quartz sand, petroleum coke and high-quality silica as the main raw materials, which are smelted at high temperature in a resistance furnace. Its hardness is between corundum and diamond, its mechanical strength is higher than corundum, and it is brittle and sharp.

Silicon carbide has four main application areas, namely: functional ceramics, advanced refractory materials, abrasives and metallurgical raw materials.

(1)As abrasives, it can be used to make abrasives, such as grinding wheels, oil stones, grinding heads, tile type, etc.

(2) As metallurgical deoxidizer and high temperature resistant material.

Silicon carbide is used in the field of abrasives

It is mainly used to make grinding wheels, sandpaper, abrasive belts, oil stones, grinding blocks, grinding heads, abrasive pastes and for grinding and polishing of monocrystalline silicon, polycrystalline silicon in photovoltaic products and piezoelectric crystals in the electronics industry, etc.

Silicon carbide is used in the field of metallurgy

It can be used as a deoxidizer for steel making and an improver for the organization of cast iron, 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 compound deoxidizer, replacing the traditional silicon powder carbon powder for deoxidation, and the original process compared to the physical and chemical properties of more stable, good deoxidation effect, so that the deoxidation time is shortened, saving energy, improve steelmaking efficiency, 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.

Silicon carbide is used in the field of 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., can also be used to make wear-resistant, corrosion-resistant, high temperature and other advanced silicon carbide ceramic materials, individual applications can also be made of rocket nozzle, gas turbine blades, etc.. In addition, silicon carbide is also one of the ideal materials for highways, airplane runways, solar water heaters, etc.

Because silicon carbide has high temperature resistance, high strength, good thermal conductivity, impact resistance, so it can also be used as a 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.. Using the characteristics of corrosion resistance, thermal shock resistance, abrasion resistance and good thermal conductivity of silicon carbide, it is used in the lining of large blast furnaces to improve the service life.

Silicon carbide is used in the field of sandblasting and rust removal

1. Surface matte treatment of steel, steel pipe, steel structure stainless steel products, sandblasting and rust removal treatment before spraying.

2. It is used for the cleaning of various molds.

3. can remove all kinds of machine parts tensile stress, increase fatigue life.

4. Semiconductor devices, plastic sealing on the tube before the tin cleaning to remove the edge of the thorn.

5. medical equipment, textile machinery and all kinds of hardware products of the shot peening light finishing processing.

6. a variety of metal tubes, non-ferrous metal precision casting cleaning and removal of burr residue.

Silicon carbide product characteristics

1. silicon carbide hardness is second only to diamond, has strong wear resistance, is the ideal material for wear-resistant pipes, impellers, pump chambers, cyclones, ore hopper lining, its wear resistance is cast iron. Rubber service life of 5-20 times is also one of the ideal materials for aviation runway.

2. the use of its thermal conductivity, thermal radiation, high thermal strength, manufacturing thin plate kiln furniture, not only can reduce the capacity of the kiln, but also improve the installed capacity of the kiln and product quality, shorten the production cycle, is the ideal indirect material for ceramic glaze baking and sintering.
