Stable chemical properties, high thermal conductivity, small thermal expansion coefficient, good wear resistance, high thermal conductivity, high breakdown electric field strength and high maximum current density.

The hardness of silicon carbide is very high, and the Mohs hardness is 9.5, which is second only to the hardest diamond in the world (10). It is a semiconductor with excellent thermal conductivity and can resist oxidation at high temperature.

There are at least 70 crystal forms of silicon carbide. Its specific gravity is 3.2g/cm3 and its sublimation temperature is relatively high (about 2700℃).

C), it will not melt under any pressure that can be reached, and its chemical activity is quite low.

Uses of silicon carbide: Silicon carbide has four main application fields, namely: functional ceramics, advanced refractories, abrasives and metallurgical raw materials.

As abrasive, it can be used as abrasive tools, such as grinding wheel, whetstone, grinding head, sand tile and so on.

Used as metallurgical deoxidizer and high temperature resistant material.

High purity single crystals can be used to manufacture semiconductors and silicon carbide fibers.
