Silicon carbide has two commonly used basic varieties, black silicon carbide and green silicon carbide, both of which belong to α-SiC. ①Black silicon carbide contains about 95% SiC, and its toughness is higher than that of green silicon carbide. It is mostly used for processing materials with low tensile strength, such as glass, ceramics, stone, refractory materials, cast iron and non-ferrous metals. ②Green silicon carbide contains more than 97% SiC and has good self-sharpening properties. In addition, there is cubic silicon carbide, which is a yellow-green crystal obtained by a special process. The abrasive tool used to make it is suitable for super-finishing of bearings.

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

1. Ceramic grinding wheel for building materials: Using its thermal conductivity, heat radiation, high thermal strength, and high thermal strength to manufacture thin-plate kiln furniture, not only can reduce the capacity of kiln furniture, but also improve the loading capacity and product quality of the kiln, and shorten the production cycle. The ideal indirect material for ceramic glazed baking and sintering.

2. Refractory material: Silicon carbide has the characteristics of corrosion resistance, high temperature resistance, 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, linings, Supports, saggars, 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 furnace, rectification furnace tray, aluminum electrolytic cell, copper melting furnace lining, arc plate for zinc powder furnace, thermocouple protection tube, etc. ; Used to make high-grade silicon carbide ceramic materials such as wear resistance, corrosion resistance and high temperature resistance; it can also be used to make rocket nozzles, gas turbine blades, etc. In addition, silicon carbide is also one of the ideal materials for solar water heaters for highways and aviation runways.

3. Abrasives: mainly used for grinding and polishing of grinding wheels, sandpapers, abrasive belts, whetstones, grinding blocks, grinding heads, grinding pastes, monocrystalline silicon, polycrystalline silicon and piezoelectric crystals in the electronics industry in photovoltaic products. .

4. Metallurgical raw materials: it can be used as a deoxidizer for steelmaking and a modifier of cast iron structure, and can be used as a raw material for the manufacture of silicon tetrachloride, which is the main raw material for the silicone resin industry. Silicon carbide deoxidizer 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 shortened, energy is saved, and the Steelmaking efficiency, improving steel quality, reducing raw and auxiliary material consumption, reducing environmental pollution, improving working conditions, and improving the comprehensive economic benefits of electric furnaces are all of great value.
