【The silicon carbide products introduction 】 :

Silicon carbide known as silicon carbide (SiC) or fire, carbon silica sand, mainly divided into the black silicon carbide and silicon carbide, green is made of quartz sand and petroleum coke or coal tar, wood chips as raw materials (need to add salt when the production of green silicon carbide) through high temperature electric resistance furnace smelting, both for the six-party crystals.

【The classification of the silicon carbide 】  :

Silicon carbide are divided into the following two:

(1) black silicon carbide containing SiC by about 95%, 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) the green silicon carbide containing SiC is about more than 97%, 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.

【The application field of silicon carbide 】 :

Silicon carbide due to the chemical performance is stable, high thermal conductivity, thermal expansion coefficient is small, wear-resisting performance is good, has the following main areas of application:

1, abrasives, mainly used for grinding wheel, abrasive paper, abrasive belt, abrasive, grinding, grinding head, grinding paste.

2, sandblasting derusting --

(1) stainless steel products, steel, steel pipe, steel structure on the surface of inferior smooth processing, sandblasting derusting treatment before spraying;

(2), for a variety of mold cleaning;

(3), semiconductor devices, encapsulation of tin on the tube before cleaning to remove edge;

(4), medical e, textile machinery and all kinds of hardware products of shot peening finishing processing;

(5), all kinds of metal, non-ferrous metal precision casting cleaning and remove burrs residue;

(6), photovoltaic products of monocrystalline silicon, polycrystalline silicon and electronic industry in piezoelectric crystal aspects such as grinding, polishing, etc.;

3, can be used as manufacture of silicon tetrachloride raw materials, is the main raw material of silicone industry.

4, physical processing materials - for 3-12 inch monocrystalline silicon, polycrystalline silicon, potassium arsenide, quartz crystal, such as wire cutting, solar photovoltaic industry, semiconductor industry, piezoelectric crystal industry physical processing materials.

5 deoxidizer, steel and iron group improver, silicon carbide deoxidizer is a new kind of compound deoxidizer, deoxidize shorter time, save energy and improve the efficiency of steel, improve the of steel, reduce raw material consumption, reduce environmental pollution, improve working conditions, improve the comprehensive economic benefits of electric furnace.

6, fire-proof material, using silicon carbide has corrosion resistance, high temperature resistance, strength, impact resistance and other properties, heat conduction performance is good, to make high-grade refractory materials, heat resistant, small volume, light weight and high strength, good energy saving effect. Can be used for various components of smelting furnace lining, high temperature furnaces, silicon carbide plate, plate, supports, sagger, silicon carbide crucible, etc.

7, ceramic materials, used to produce wear-resisting, corrosion resistant, high temperature resistance and other advanced silicon carbide ceramic materials; Silicon carbide ceramics of good chemical corrosion resistance, high strength, high hardness, good wear resistance, small friction coefficient, and high temperature resistance, thus making ring is an ideal material.

8, high-temperature indirect heating - using silicon carbide with high temperature resistance, strength, good thermal performance, impact resistance, high-temperature indirect heating, such as strong retort furnace, tray distillation furnace, aluminium electrolyzer, copper melting furnace lining, furnace zinc powder with arc plate, the thermocouple protection tube, etc.

9, wear-resisting pipe runway - silicon carbide hardness is second only to diamond, strong wear resistance, is wear-resisting pipe, the impeller, pump room, cyclone, ore bucket lined with ideal material, in addition, silicon carbide and highway, aviation airport runway solar water heater, etc. One of the ideal material.

10, building materials, ceramic grinding wheel industry, using its coefficient of thermal conductivity, thermal radiation, high temperature strength properties, manufacturing sheet kiln furniture, not only can reduce the capacity of kiln furniture, also improves the loading capacity of the kiln and the product , shorten the production cycle, is the ideal of ceramic glaze baking sintering indirect materials.

11, energy saving, good thermal conductivity and thermal stability, heat exchanger, burnup decreased by 20% and saving fuel by 35%, to improve productivity by 20-30%, especially mine concentrator with the discharge pipeline, the wear-resisting degree of wear resistant material is ordinary 6 -- 7 times.

12 - single crystals of high purity, and other fields can be used to manufacture semiconductors, silicon carbide fiber, the lightning rod, circuit components, the application of high temperature and ultraviolet detection apparatus, structure, material, astronomy, disc brakes, clutch, diesel particle filter, filaments pyrometer, ceramic film, cutting tools, heating element, nuclear fuel, jewelry, steel, gear, catalyst supporter, etc, also can make the rocket nozzle, gas turbine blades, etc.
