Black Silicon Carbide SIC95 Description
Silicon carbide is also known as carbonite. In the contemporary C, N, B and other non-oxide high-tech refractory raw materials, silicon carbide is the most widely used, the most economical - kind, can be called gold steel sand or refractory sand. At present, China's industrial production of silicon carbide is divided into black silicon carbide and green silicon carbide two kinds, are hexagonal crystals, the specific gravity of 3.20~3.25, microhardness of 2840~3320kg/mm2.

Properties of silicon carbide: chemical stability, high thermal conductivity, low thermal expansion coefficient, good wear resistance, high thermal conductivity, high collapse electric field strength and high maximum current density. Use of silicon carbide: Silicon carbide has four main application areas, namely: functional ceramics, high-grade refractory materials, abrasives and gold treatment raw materials.
1, mechanical properties: high hardness (KR hardness of 3000kg/mm2), can cut ruby; High wear resistance, second only to diamond.
2, thermal performance: thermal conductivity is more than copper metal, is 3 times Si, is 8 to 10 times GaAs, good heat dissipation performance, very important for high-power devices. The thermal stability of SiC is high, and it is impossible to melt SiC under normal pressure.
3, chemical properties: corrosion resistance is very strong, at room temperature can resist almost any known corrosive agent. The surface of SiC is easy to oxidize to form a thin layer of SiO2, which can prevent its further oxidation. When it is higher than 1700℃, this layer of oxide film melts and oxidation reaction occurs rapidly.
4, electrical performance: 4H-SiC and 6H-SiC bandgap is about 3 times that of Si, is 2 times that of GaAs; The breakdown electric field strength is one order of magnitude higher than Si, and the saturated electron drift speed is 2.5 times that of Si. 4H-SiC has a wider band gap than 6H-SiC. The following table compares the characteristics of several semiconductor materials.
