The service life is 1 to 2 times; the advanced refractory material made of it is thermal shock resistant, small in size, light in weight, high in strength, and has good energy saving effect. It is a deoxidizer with better performance compared with the same period last year. It can speed up the steelmaking speed, facilitate the control of chemical composition and improve the quality of steel. In addition, silicon carbide is also widely used in the production of silicon carbide rods for electric heating elements.
Silicon carbide is very hard and has excellent thermal conductivity. It is a semiconductor and can resist oxidation at high temperatures. use
(1) As an abrasive, it can be used to make abrasive tools, such as grinding wheels, whetstones, grinding heads, sand tiles, etc.
(2) As metallurgical deoxidizer and high temperature resistant material.
Silicon carbide has four main application areas, namely: functional ceramics, advanced refractory materials, abrasives and metallurgical raw materials. At present, silicon carbide rough materials can be supplied in large quantities and cannot be regarded as high-tech products. However, the application of nano-scale silicon carbide powder with extremely high technical content is unlikely to achieve economies of scale in a short time.
(3) High-purity single crystals can be used to manufacture semiconductors and silicon carbide fibers.
