Silicon carbide due to chemical stability, high thermal conductivity, low thermal expansion coefficient, good wear resistance, mainly has the following main application field:
(1), mainly for the production of grinding wheel abrasive, sandpaper, abrasive belt, oilstone, grinding block, grinding head, grinding paste.
(2) blasting -
1, iron and steel, steel pipe, steel structure, stainless steel products, surface polishing treatment, spraying sand blasting treatment;
2, used for a variety of mold cleaning;
3, semiconductor devices, plastic tube on the tin before cleaning to remove burrs;
4, medical equipment, textile machinery and all kinds of hardware products of shot peening strengthening polishing processing;
5, all kinds of metal pipes, non-ferrous metal casting cleaning and removal of burr residue;
6, monocrystalline silicon, polycrystalline silicon photovoltaic products and electronic industry piezoelectric and other aspects of the grinding, polishing etc.;
(3) can be used for manufacturing four chlorinated silicon raw materials, is the main raw material for silicon resin industry.
(4) processing materials engineering -- for 3 - 12 inch silicon, polycrystalline silicon, GaAs, quartz crystal, line cutting, solar photovoltaic industry, semiconductor industry, piezoelectric crystal industry engineering materials.
(5) steel deoxidizer and iron microstructure modifier - SiC deoxidizer is a new type of strong deoxidizers, the deoxidation time is shortened, energy conservation, improve the efficiency of steel-making, improve steel quality, reduce raw material consumption, reduce environmental pollution, improve working conditions, enhance the comprehensive economic benefits of electric furnace.
(6) using silicon carbide refractories -- has corrosion resistance, high temperature resistance, high strength, good thermal conductivity, impact resistance and other characteristics, made of high-level refractory material used, thermal shock, small volume, light weight and high strength, good energy saving effect. Can be used for a variety of smelting furnace, high temperature furnace, silicon carbide board member, lining board, support, saggar, silicon carbide crucible etc..
(7) for the production of ceramic materials, wear and corrosion resistance, and other advanced silicon carbide ceramics; silicon carbide ceramic chemical corrosion resistance, high strength, high hardness,good wear resistance, low friction coefficient, and high temperature resistance, thus is the ideal material for sealing ring.
(8) high temperature indirect heating materials -- using silicon carbide has the advantages of high temperature resistance, high strength, good thermal conductivity, anti impact, high temperature and indirect heating materials, such as vertical distillation furnace, refining furnace tray, electrolytic aluminum, copper melting furnace lining, with the arc plate zinc powder furnace, thermocouple protection tube.
(9) wear resistant pipe line - silicon carbide hardness second only to diamond, with strong wear resistance, is wear-resisting pipe, impeller, pump chamber, cyclone, an ideal material, ore bucket lined in addition, silicon carbide is one of highway, aviation runway solar water heaters such as the ideal material.
(10) building materials ceramic grinding wheel industry -- the coefficient of thermal conductivity, thermal radiation characteristics., high strength, manufacturing plate kiln, not only can reduce the kiln capacity, but also improve the capacity of furnace and the quality of products, shorten the production cycle, is indirect material ceramic glaze sintering to bake.
(11) energy efficiency -- the good thermal conductivity and thermal stability, heat exchanger, fuel consumption is reduced by 20%, save fuel 35%, the productivity of 20-30%, especially for conveying pipeline discharge mine concentrator is put inside, its wear-resisting degree is 6--7 times that of ordinary wear-resistant materials.
(12) other areas of high purity single crystal, can be used in the manufacture of semiconductor manufacturing, silicon carbide fiber, the lightning rod, circuit elements, application temperature, UV detector, structural materials, astronomy, disc brake, clutch, diesel particulate filter, filament pyrometer, ceramic film, cutting tools, heating element, nuclear fuel, jewelry, steel, protective gear, catalyst carrier and other areas, also can make the rocket nozzle, gas turbine blades.
