Silicon Carbide Powder

Material Function:

Silicon carbide is an inorganic substance with a chemical formula of SiC. It is made by high temperature smelting of raw materials such as quartz sand, petroleum coke (or coal coke), and wood chips (salt is needed to produce green silicon carbide) through a resistance furnace. Silicon carbide also exists in nature, a rare mineral, moissanite. Among the non-oxide high-tech refractory materials such as C, N, and B, silicon carbide is the most widely used and most economical one.

Silicon carbide (SiC), also known as carborundum (/ˌkɑːrbəˈrʌndəm/), is a semiconductor containing silicon and carbon. It occurs in nature as the extremely rare mineral moissanite. Synthetic SiC powder has been mass-produced since 1893 for use as an abrasive. Grains of silicon carbide can be bonded together by sintering to form very hard ceramics that are widely used in applications requiring high endurance, such as car brakes, car clutches and ceramic plates in bulletproof vests. Electronic applications of silicon carbide such as light-emitting diodes (LEDs) and detectors in early radios were first demonstrated around 1907. SiC is used in semiconductor electronics devices that operate at high temperatures or high voltages, or both. Large single crystals of silicon carbide can be grown by the Lely method and they can be cut into gems known as synthetic moissanite.

Application:

There are four main application areas, including functional ceramics, advanced refractories, abrasives and metallurgical raw materials.

1. As an abrasive, it can be used to make abrasive tools, such as grinding wheels, oilstones, grinding heads, sand tiles, etc.

2. Silicon carbide is a new type of strong composite deoxidizer, which replaces the traditional silicon powder and carbon powder for deoxidation. Compared with the original process, the physical and chemical properties are more stable, the deoxidation effect is good, the deoxidation time is short, the energy is saved, and the refining is improved. Steel efficiency, improve the quality of steel, reduce the consumption of raw and auxiliary materials, reduce environmental pollution, improve working conditions, and increase the energy and economic benefits of electric furnaces.

3. High-purity single crystal, which can be used to manufacture semiconductors and silicon carbide fibers.

4. Used for wire cutting of 3-12 inch monocrystalline silicon, polycrystalline silicon, potassium arsenide, quartz crystal, etc. Engineering processing materials for the solar photovoltaic industry, semiconductor industry, and piezoelectric crystal industry.

5. Lightning rods, circuit components, ultraviolet light detectors, structural materials, astronomy, disc brakes, clutches, diesel particulate filters, filament pyrometers, ceramic films, cutting tools, heating elements, nuclear fuel, jewelry, steel, Protective gear, catalyst support and other fields.

6. The use of silicon carbide has the characteristics of corrosion resistance, high temperature resistance, high strength, high strength, good thermal conductivity, and impact resistance. On the one hand, silicon carbide can be used for various smelting furnace linings, high temperature furnace components, silicon carbide plates, backing plates, and brackets. , Saggers, silicon carbide crucibles, etc.

7. The field of high temperature refractory materials. For example, high-temperature indirect heating materials in the non-ferrous metal smelting industry, such as vertical distillation furnaces, rectification furnace trays, etc.

8. The building materials ceramic grinding wheel industry uses its thermal conductivity, heat radiation, and high strength characteristics to manufacture thin plate kiln furniture, which can not only reduce the capacity of the kiln furniture, but also improve the bearing capacity and product quality of the kiln furniture, and shorten the production cycle. It is an ideal indirect material for ceramic glaze baking and sintering.

Silicon Carbide Deoxidizer

Silicon carbide is a new type of strong composite deoxidizer, which replaces the traditional silicon powder carbon powder for deoxidation. Compared with the original process, the physical and chemical properties are more stable, the deoxidation effect is good, the deoxidation time is short, energy saving, and steelmaking efficiency are improved. , Improve the quality of steel, reduce the consumption of raw and auxiliary materials, reduce environmental pollution, improve working conditions, and increase the energy and economic benefits of electric furnaces.

Silicon carbide balls are wear-resistant, non-polluting, improve the stability of raw materials, reduce the thickness of the mill and the volume of the balls, and increase the effective volume of the mill by 15%-30%.
