Description

Our company silicon carbide due to the natural content of very little, so the main Our company mostly artificial silicon carbide. The most common method is to quartz sand is mixed with coke, which use silica and petroleum coke, add salt and wood chips, into an electric furnace and heated to a high temperature of about 2000°C, after various chemical processes to obtain silicon carbide powder.

Our company silicon carbide great hardness, Mohs hardness of 9.5, second only to the world's most hard diamond (10), with excellent thermal conductivity, is a semiconductor, resistant to oxidation at high temperatures. From this we can see that Our company Silicon carbide has chemical stability, high thermal conductivity, thermal expansion coefficient, good wear resistance, corrosion resistance, high temperature, high strength, good thermal conductivity, impact resistance and other characteristics.

Our company silicon carbide is mainly divided into the following two:
(1)Black silicon carbide: containing about 95% SiC, which is higher than the toughness of green silicon carbide, mostly for processing low tensile strength materials such as glass, ceramics, stone, refractories, cast iron and non-ferrous metals.
(2)Green silicon carbide: SiC containing more than about 97%, good self-sharpening, mostly for processing hard alloy, titanium alloy and optical glass, also used for honing cylinder liners and grinding high-speed steel cutting tools.

Our company silicon carbide purposes:
1:Abrasives aspects: Our company Silicon carbide has good wear resistance, strength and other characteristics, so Our company mainly for the production of silicon carbide grinding wheel, sandpaper, grinding paste and photovoltaic products monocrystalline silicon, polycrystalline silicon and electronics industries piezoelectric crystals and other aspects of grinding and polishing.
2:Chemical industry: from silicon carbide Our company features we can know, do improver steelmaking deoxidizer and cast iron structure of Our company available silicon carbide, can be used as raw material for the manufacture of silicon tetrachloride, silicon resin is the main industry raw material.
3:Wear-resistant,fire-resistant and corrosion-resistant materials: the use of silicon carbide Our company resistant to corrosion, high temperature, high strength, good thermal conductivity, impact resistance and other characteristics, Our company silicon carbide on the one hand can be used for a variety of smelting furnace lining, high temperature kiln member or the like. On the other hand Our company silicon carbide can be used for high-temperature indirect heating of the material non-ferrous metal smelting industry. Our company silicon carbide for the production of wear-resistant, corrosion resistance, high temperature and other advanced silicon carbide ceramic material. Our company silicon carbide can also making rocket nozzles, turbine blades. In addition, silicon carbide is Our company highway, one of the ideal material for aviation runway solar water heaters and the like.
4:Non-ferrous metals: Our company use of silicon carbide with a high temperature, high strength, good thermal conductivity, impact resistance, it can be used as high-temperature indirect heating materials.
5:Steel: the use of silicon carbide Our company corrosion resistance, thermal shock resistance, abrasion, and good thermal conductivity, it is not only for the production of large-scale furnace lining, but also improve its service life.
6:Metallurgical beneficiation aspects: Our company silicon carbide hardness only to diamond, has strong wear resistance, abrasion-resistant silicon carbide thus Our company piping, ideal material for ore bucket lined, silicon carbide is Our company aviation runway It is one of the ideal material.
7:Materials ceramic wheel industry: the use of silicon carbide Our company thermal conductivity, high strength characteristics of high fever, manufacturing sheet kiln, kiln can not only reduce capacity, but also increased the installed capacity of the furnace and product quality, shorten the production cycle therefore Our company sintered silicon carbide ceramic glazed roasted over indirect material.
