Silicon carbide thermal conductivity?

Silicon carbide thermal conductivity?
Silicon carbide is a high -performance ceramic material with excellent thermal conductivity. Its thermal conductivity is as high as 270 W/m · K, which is 3 times the copper, 4 times the aluminum, and 20 times the steel. Therefore, it is widely used in the heat dissipation and thermal conductivity in extreme environments such as high temperature, high pressure, and high -speed.
The heating coefficient of silicon carbide is mainly due to the special nature of its crystal structure. The silicon crystal structure is a hexagonal crystal system. Its lattice constant is small and the atomic spacing is closer. Therefore, the interaction force between the atoms is strong, resulting in fast thermal conductivity. In addition, the key structure between carbon and silicon atoms in silicon crystals is also an important factor that leads to high thermal conductivity. The key structure between carbon atoms and silicon atoms in silicon crystals is a covalent bond. This key structure has high strength and stability, which can effectively transmit heat energy.
The high thermal coefficient of silicon carbide makes it have a wide range of application prospects in extreme environments such as high temperature, high voltage, and high speed. For example, in the field of aerospace, silicon carbide can be used to manufacture high -temperature engine components, heat conductors, radiator, etc.; in the electronics field, silicon carbide can be used to create high -power semiconductor devices, high bright LED radiator, etc. Silicon carbide can be used to make high -temperature reactors and catalyst carriers

In addition to the high thermal conductivity, silicon carbide also has other excellent performance, such as high hardness, high strength, high wear resistance, high chemical stability, etc. These properties make silicon carbide have a wide range of application prospects in various fields. With the continuous progress of science and technology, the scope of silicon carbide will become more and more extensive, bringing more convenience and benefits to human production and life.
