company news about Properties of silicon carbide

Properties of silicon carbide:
Silicon carbide because of its stable chemical properties, high thermal conductivity, small thermal expansion coefficient, good wear resistance, in addition to abrasive, there are many other uses. Pure silicon carbide is colorless, and industrial production of brown to black is due to the impurity of iron. The iridescent sheen of the crystal is due to a protective layer of silica on its surface.

Application category of silicon carbide:
Silicon carbide has four main application areas, namely: functional ceramics, advanced refractory materials, abrasives and metallurgical raw materials. Coarse SIC material can be supplied in large quantities, can not be counted as high-tech products, and the application of nano-sized SIC powder with very high technical content is impossible to form economies of scale in a short time.
(1) As abrasive, it can be used as abrasive tools, such as grinding wheel, whetstone, grinding head, sand tile, etc.
⑵ As a metallurgical deoxidizer and high temperature resistant material.
(3) High purity single crystal, can be used to manufacture semiconductors, manufacturing silicon carbide fiber.
