Sublimation method can be obtained directly with silicon carbide powder mass and large area heavily sb-doped silicon carbide.
With heavily sb-doped silicon carbide to produce green or blue light-emitting diodes, field effect transistor, bipolar transistor.
With silicon carbide fibers can be made into radar absorbing material and broad prospects in military industry. Silicon carbide superfinishing fine powder is an ideal material to production of silicon carbide ceramics. Silicon carbide ceramics with excellent mechanical properties at room temperature, such as high bending strength, excellent oxidation resistance, corrosion resistance, high wear resistance and low friction coefficient, and high temperature mechanical properties (strength, creep resistance, etc.) is the best material of ceramic material, known as whisker reinforcement can improve the toughness and strength of silicon carbide.
Silicon Carbide Features
The characteristics of black silicon carbide: big furnace smelting, refining time is long, crystallization, crystal particles is large, high purity, less impurities; High strength, good durability; After pickling, washing, cleanliness;
Through special processing of high product purity, strength, higher grinding ability is stronger.
Green silicon carbide is suitable for the killing of copper, aluminium, jewel, optical glass, ceramics and other hard alloy, metallic and hard and brittle non-metallic materials; Micro powder can also be used as a ceramic material.
Silicon carbide (SiC) is using quartz sand and petroleum coke or coal tar, wood chips as raw material through high temperature electric resistance furnace smelting.
Silicon carbide in nature there is also a rare mineral mo SangShi, also called moissanite. In contemporary C, N, B the oxide refractory raw materials in the high technology, such as silicon carbide as the most widely used, one of the most economic, can be called corundum or refractory sand.
Application Difference between Black Silicon Carbide and Green Silicon Carbide
Green silicon carbide silicon carbide black silicon carbide and two common basic varieties, belong to SiC.
1, black silicon carbide containing SiC by about 98.5%, its toughness is higher than the green silicon carbide, mostly used for processing low tensile strength of material, such as glass, ceramics, stone, refractory material, cast iron and nonferrous metal, etc.
2, green silicon carbide containing SiC99 % above, good self-sharpening, mostly used for processing hard alloy, titanium alloy and optical glass, also used for honing cylinder jacket and fine grinding HSS cutting tools.
3, and cubic silicon carbide, it is a special process for making yellow crystals, to make the abrasive tool suitable for bearing the superfinishing, can make the surface roughness from a processing Ra32 ~ 0.16 microns to Ra0.04 ~ 0.02 microns.
Because silicon carbide chemical stable performance, high thermal conductivity, thermal expansion coefficient, wear-resisting performance is good, there are mainly four big application field, namely, functional ceramics, refractories, abrasives, metallurgical raw materials. Silicon carbide raw material supply can have a lot of, can't calculate high-tech products, and the application of high technology content of nano-sized sic powder short time can't form scale economy.
1, as abrasive, abrasive tool can be used to do, such as grinding wheel, whetstone, grinding head, sand tile, etc.
2, as metallurgical deoxidizer and high temperature resistant material.
3, single crystals of high purity, can be used in the manufacture of semiconductor, the manufacture of silicon carbide fibers.
4, for 3-12 inch monocrystalline silicon, polycrystalline silicon, potassium arsenide, quartz crystal wire cutting, etc. Solar photovoltaic industry, semiconductor industry, piezoelectric crystal industry physical processing materials.
5, used in semiconductor, the lightning rod, circuit components, the application of high temperature and ultraviolet detection apparatus, material structure, astronomy, disc brakes, clutch, diesel particle filter, filaments pyrometer, ceramic film, cutting tools, heating element, nuclear fuel, jewelry, steel, gear, catalyst supporter, and other fields.
