Silicon Carbide: It is an inorganic material with the chemical formula SiC, which is smelted with quartz sand, petroleum coke (or coal coke), wood chips (salt is needed to produce green silicon carbide) and other raw materials through high temperature smelting in a resistance furnace.
Silicon carbide due to its stable chemical properties, high thermal conductivity, small coefficient of thermal expansion, good wear resistance, in addition to abrasives, there are many other uses, such as: a special process to the silicon carbide powder coated in the impeller of the hydraulic turbine or the inner wall of the cylinder body can improve its wear resistance and extend the service life of 1 to 2 times; used to make high-level refractories, heat shock, small size, light weight and high strength, energy-saving effect is good.
(Containing SiC about 85%) is an excellent deoxidiser, it can be used to accelerate the speed of steelmaking, and to facilitate the control of chemical composition, improve the quality of steel. In addition, silicon carbide is also used in large quantities in the production of electric heating elements silicon carbon rods. 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 oxidation resistance.
