Introduction of silicon carbide
Silicon carbide with quartz sand and petroleum coke or coal tar, wood chips in the Canon of high-temperature resistance furnace smelting from such as raw materials, are the six-party crystals.Silicon carbide known as silicon carbide or refractory sand, silica, carbon is mainly divided into the black silicon carbide and green silicon carbide:
1, black silicon carbide containing SiC by about 95%, its toughness is higher than the green silicon carbide, black silicon carbide is used for processing low tensile strength of materials, such as glass, ceramics, stone, refractory material, cast iron and nonferrous metal, etc.;
2, green silicon carbide containing SiC98 % above, good self-sharpening, green silicon carbide is used for processing hard alloy, titanium alloy and optical glass, green silicon carbide for honing cylinder jacket and fine grinding HSS cutting tools.
Characteristics of silicon carbide
Silicon carbide has stable chemical performance, high thermal conductivity, small thermal expansion coefficient, good wear resistance, corrosion resistance, high temperature resistance, strength, good thermal performance, impact resistance and other properties.?
Silicon carbide purpose
1, the abrasive cutting tools: due to the durability and low cost silicon carbide, used as a commonly used abrasive in modern gem processing.Silicon carbide because of its hardness to make it in the manufacturing industry, such as grinding wheel cutting, honing, water knife cutting and sand grinding process, the silicon carbide particles laminated on the paper can be made into sand paper and skateboard grip tape.Can also be used to used to make grinding wheel, abrasive paper, abrasive belt, abrasive, grinding, grinding head, grinding paste, etc.
2, structure, material: silicon carbide material can be used to make composite armor and ceramic plate in bulletproof vests.
3, astronomy: silicon carbide with low thermal expansion coefficient, high hardness, rigidity and thermal conductivity make it can be used as a telescope mirror material.By chemical vapor deposition manufacturing diameter of 3.5 meters and 2.7 meters of polycrystalline silicon carbide disk has been installed in the herschel space observatory respectively and the stratosphere infrared observatory on large astronomical telescope.
4, catalyst carrier, the antioxidant properties of silicon carbide itself and cubic beta SiC has large specific surface area makes it can be used as the carrier of heterogeneous catalyst.By rice husk char synthesis of beta SiC has been used as a carrier of heterogeneous catalysts used in catalytic such as normal butane oxidation produce maleic anhydride such hydrocarbon oxidation reaction.
5, abrasives, mainly used for grinding wheel, abrasive paper, abrasive belt, abrasive, grinding, grinding head, grinding paste, and photovoltaic products of monocrystalline silicon, polycrystalline silicon and electronic industry in piezoelectric crystal aspects such as grinding, polishing, etc.
6, chemical industry, can be used as tissue conditioner, steelmaking deoxidizer and cast iron can be used as manufacture of silicon tetrachloride raw material, is the main raw material of silicone industry.Silicon carbide deoxidizer is a new kind of compound deoxidizer, replaced the traditional solid silicon powder carbon powder, and compared with the original process of various physical and chemical performance is more stable, deoxidization effect is good, deoxidize shorter time, save energy and improve the efficiency of steel, improve the quality of steel, reduce raw material consumption, reduce environmental pollution, improve working conditions, improve the comprehensive economic benefits of the electric furnace has important value.
7, energy saving: with good thermal conductivity and thermal stability, heat exchanger, burnup decreased by 20% and saving fuel by 35%, to improve productivity by 20-30%, especially at mill plant with the discharge pipeline, the wear-resisting degree of wear resistant material is ordinary 6 -- 7 times.
8, refractory material, using silicon carbide has corrosion resistance, high temperature resistance, strength, good thermal conductivity and impact resistance and other properties, silicon carbide on the one hand, can be used for all kinds of smelting furnace lining, high temperature furnaces artifacts, silicon carbide plate, plate, supports, sagger, silicon carbide crucible, etc.On the other hand can be used in non-ferrous metal smelting industry of high-temperature indirect heating, such as vertical distillation furnace, furnace distillation tray, aluminium electrolyzer, copper melting furnace lining, furnace zinc powder with arc plate, the thermocouple protection tube, etc.;Used to produce wear-resisting, corrosion resistant, high temperature resistance and other advanced silicon carbide ceramic materials.
