Description

Introduction to Silicon Carbide
       Silicon carbide silicon carbide and green silicon carbide two common base of the varieties, are α-SiC. ① black silicon carbide containing about 95% of SiC, its toughness is higher than the green silicon carbide, mostly used for processing low tensile strength materials such as glass, ceramics, stone, refractories, cast iron and nonferrous metals. ② green silicon carbide containing about 97% or more of SiC, self-sharpening, mostly for processing carbide, titanium and optical glass, but also for honing cylinder sets and grinding high-speed steel cutting tools. In addition, there are cubic silicon carbide, which is produced by special process of yellow-green crystal, for the production of abrasive bearings for ultra-finishing, the surface roughness from Ra32 ~ 0.16 micron processing time to Ra0.04 ~ 0.02 microns. Silicon carbide because of chemical stability, high thermal conductivity, thermal expansion coefficient, wear resistance, in addition to abrasive, there are many other uses, such as: a special process of silicon carbide powder coating on the turbine impeller or The inner wall of the cylinder block can improve its abrasion resistance and prolong service life by 1 to 2 times. It is made of high-grade refractory material, heat shock resistant, small volume, light weight, high strength and good energy-saving effect. Low-grade silicon carbide (containing about 85% of SiC) is an excellent deoxidizer, it can speed up steelmaking speed, and easy to control the chemical composition, improve the quality of steel. In addition, a large number of silicon carbide is also used in the production of silicon carbide heating element.
     Green silicon carbide abrasives are harder and brittle than black silicon carbide. They are sharper and have a sharp cutting edge, making it easy to cut into the workpiece. It is mainly used for the manufacture of ceramic and resin grinding wheel, the grinding of cemented carbide tool and workpiece, the grinding of thread grinding and its tools, the grinding of agate, the gemstone bearing of watch, the jewelery of high grade jewelry, heavy metal (such as germanium) Of the cutting and free grinding, the ground pressure and wear resistance.
Product Categories
     Black silicon carbide containing about 98% of SiC, its toughness is higher than the green silicon carbide, mostly used for processing low tensile strength materials such as glass, ceramics, stone, refractory materials, cast iron and nonferrous metals.
     Green silicon carbide containing more than 98.5% of SiC, since the sharpness, and most of the processing of cemented carbide, titanium and optical glass, but also for honing cylinder sets and high-speed steel grinding tool. In addition, there are cubic silicon carbide, which is produced by special process of yellow-green crystal, for the production of abrasive bearings for ultra-finishing, the surface roughness from Ra32 ~ 0.16 micron processing time to Ra0.04 ~ 0.02 microns.
Silicon Carbide Uses
     1, Abrasives:
     It is mainly used for the grinding and polishing of grinding wheel, sand paper, abrasive belt, whetstone, grinding block, grinding head, polishing paste and piezoelectric crystal in monocrystalline silicon, polysilicon and electronic industry of photovoltaic products.
     2, chemical aspects:
      Can be used for steel-making deoxidizer and the improvement of cast iron organization, can be used for the manufacture of silicon tetrachloride raw materials, silicon resin industry is the main raw material. The deoxidizing agent is a new type of strong compound deoxidizer which replaces the traditional silicon powder for deoxidization. Compared with the original technology, the silicon carbide deoxidizer is more stable and has better deoxidizing effect, shortens the time of deoxidation, saves energy and improves Improve the quality of steel, reduce the consumption of raw and auxiliary materials, reduce environmental pollution, improve the working conditions, improve the comprehensive economic benefits of the electric furnace are of great value.
     3, wear-resistant, fire-resistant and corrosion-resistant materials:
     The use of silicon carbide with corrosion resistance, high temperature, high strength, good thermal conductivity, impact resistance and other characteristics, silicon carbide can be used for a variety of smelting lining, high temperature furnace components, silicon carbide plate, liner, support pieces, , Silicon carbide crucible and so on. On the other hand can be used for non-ferrous metal smelting industry, high-temperature indirect heating materials, such as vertical tank distillation furnace, rectifier tray, aluminum cell, copper melting furnace lining, zinc powder furnace arc plate, thermocouple protection tube ; For the production of wear-resistant, corrosion resistance, high temperature and other advanced silicon carbide ceramic materials; also can make rocket nozzles, gas turbine blades. In addition, silicon carbide is also the highway, airplane runway, such as solar water heaters, one of the ideal material.
     4, non-ferrous metals:
     The use of silicon carbide with high temperature, high strength, good thermal conductivity, impact resistance, as indirect heating of high temperature materials, such as the hard tank distillation furnace, rectifier tray, aluminum cell, copper melting furnace lining, Type boards, thermocouple protection tube.
     5, steel:
      The use of silicon carbide corrosion resistance, thermal shock resistance wear, good thermal conductivity characteristics, for large blast furnace lining to improve the service life.
     6, metallurgical processing aspects:
     The hardness of silicon carbide is second only to diamond, which has strong wear resistance, it is the ideal material for wear-resisting pipe, impeller, pump room, cyclone, mine bucket lining, its abrasion resistance is cast iron. - 20 times & def is also an ideal material for air flight runway.
     7, building materials, ceramic grinding wheel industry:
     The use of its thermal conductivity, thermal radiation, high heat intensity of the characteristics of the production of thin-plate kiln furniture, not only can reduce kiln capacity, but also to improve the furnace capacity and product quality and shorten the production cycle, ceramic glazed baking sintering Ideal for indirect materials.
 Energy-saving: the use of good thermal conductivity and thermal stability, as heat exchangers, fuel consumption by 20%, 35% fuel savings, the productivity increased by 20-30%, especially in the mining plant discharge pipe with the release of its Wear-resistant materials is the general level of 6 - 7 times.
     8, jewelry:
     Synthetic Moissanite (Synthetic Moissanite), also known as the synthesis of mosaic stone, synthetic carbon silica (chemical composition SiC), 0.104 dispersion than diamonds (0.044), refractive index 2.65-2.69 (2.42 diamonds), diamond and diamond with the same gloss, "Fire color" stronger than any previous imitation closer to the diamond.
Precautions
      1, transport and handling: Carbide in the transport process, not with the hook drag, should be mixed with hard material to prevent, not a strong vibration, friction, step on, smashing, throwing should be light loading and unloading, to reduce packaging broken ,Affect.
      2, Storage: Should be stored in a cool dry place, to prevent rupture inside and outside the bag, to prevent moisture and other substances, the use of effects, storage away from sources of pollution.
      3, non-flooding: silicon carbide is a senior abrasive, so in the transport, storage and use of the process, must be absolutely prevent flooding, due to flooding, a serious impact on the use of results.
