Silicon carbide due to stable chemical properties, high thermal conductivity, small thermal expansion coefficient, good wear resistance, in addition to abrasive, there are many other uses, such as: with a special process to the silicon carbide powder coated on the inner wall of the turbine impeller or cylinder body, can improve its wear resistance and extend the service life 1 ~ 2 times; Used to make high-grade refractory material, heat resistance, small size, light weight and high strength, good energy saving effect. Low-grade silicon carbide (containing about 85% SiC) is an excellent deoxidizer, which can speed up steelmaking, facilitate control of chemical composition, and improve the quality of steel. In addition, silicon carbide is also widely used in the production of electric heating element silicon carbon rod.
Silicon carbide hardness is very large, Mohs hardness of 9.5, second only to the world's hardest diamond (10), has excellent thermal conductivity, is a semiconductor, high temperature can resist oxidation.
Silicon carbide (SiC) has become an important abrasive because of its great hardness, but its application range is more than the general abrasive. For example, its high temperature resistance and thermal conductivity have become one of the preferred kiln materials for tunnel kiln or shuttle kiln, and its electrical conductivity has made it an important electric heating element. The preparation of SiC products must first prepare SiC smelting block [or: SiC particles, because it contains C and super hard, so SiC particles used to be called: emery. But note: It is different in composition from natural emery (garnet). In industrial production, SiC smelting block is usually quartz, petroleum coke and other raw materials, auxiliary recovery materials, spent materials, through grinding and other processes to become a reasonable ratio and appropriate particle size of the charge (in order to adjust the permeability of the charge need to add an appropriate amount of wood chips, the preparation of green silicon carbide also add an appropriate amount of salt) by high temperature preparation. The thermal equipment for preparing SiC smelting block at high temperature is a special silicon carbide electric furnace, whose structure consists of the bottom of the furnace, an end wall with electrodes on the inner surface, a detachable side wall, and a furnace core body (all called: The electric heating body in the center of the electric furnace is generally composed of graphite powder or petroleum coke installed in the center of the charge according to a certain shape and size, generally circular or rectangular. Both ends of the furnace are connected with electrodes. The firing method used in the electric furnace is commonly known as: When it is energized, it starts heating, the furnace core temperature is about 2500 ° C, or even higher (2600 ~ 2700 ° C), and the SiC is synthesized when the charge reaches 1450 ° C (but SiC is mainly formed at ≥1800 ° C), and CO is released. However, when the SiC is ≥2600ºC, it will decompose, but the decomposed Si will form SiC with the C in the charge. Each group of electric furnaces is equipped with a set of transformers, but the production of only a single electric furnace power supply, in order to adjust the voltage according to the electrical load characteristics to basically maintain constant power, high-power electric furnaces to heat for about 24 hours, after the power failure to generate SiC reaction is basically over, and then after a period of cooling can be removed side walls, and then gradually take out the charge. [3]
The charge after high temperature calcination from outside to inside is: Unreacted material (plays a thermal insulation role in the furnace), silicon carbide oxide (semi-reactive material, the main component is C and SiO), adhesive layer (is a very tight material layer, the main component is C, SiO2, 40% ~ 60%SiC and Fe, Al, Ca, Mg carbonate), amorphous layer (the main component is 70% ~ 90% SiC, And it is cubic SiC that is β-sic, the rest is C, SiO2 and Fe, A1, Ca, Mg carbonate), the second grade SiC layer (the main composition is 90% ~ 95%SiC, the layer has generated hexagonal SiC, but the crystal is small, very fragile, can not be used as an abrasive), the first grade SiC (SiC content <96%, And it is hexagonal SiC that is a coarse crystal of SiC), core graphite. In the above layers, the unreacted material and a part of the silicon carbide layer are usually collected as spent material, and the other part of the silicon carbide layer is collected together with the amorphous material, the second grade product, and the part of the adhesive material as the return charge, and some of the adhesive material that is very tight, large block degree and more impurities is abandoned. The first-grade product is graded, coarse crushing, fine crushing, chemical treatment, drying and screening, and magnetic separation to become a variety of particle size of black or green SiC particles. To make silicon carbide powder but also through the water separation process; To make silicon carbide products also go through the process of molding and sintering.
