Application of silicon carbide in heat conduction materials

Silicon carbide has a broad application 

Silicon carbide (SiC) has a broad application prospect in semiconductor, nuclear energy, national defense and space technology due to its good wear resistance, high temperature mechanical properties, oxidation resistance and other properties.  

With the development of society and the progress of science and technology, electronic equipment and instruments tend to be more and more precise, miniaturization and high performance, and put forward new requirements for heat conduction and heat dissipation.  

When electronic devices are working, heat will inevitably be generated, and the working efficiency of electronic devices will decrease due to the increase of their working temperature. If the heat dissipation problem is not solved in time, electronic devices will not work efficiently or even be damaged.  

Silicon carbide has high thermal conductivity, silicon carbide not only has high thermal conductivity, but also has excellent thermal stability and corrosion resistance.  Using the thermal conductivity of silicon carbide, it can be used in the substrate material of semiconductor devices, high thermal conductivity ceramic materials, heater and heating plate of semiconductor processing, nuclear fuel and compressor pump.  

Silicon carbide is an important basic material of the third generation semiconductor industry. Power devices with it as the core have the characteristics of high voltage resistance, high temperature resistance, low loss, high efficiency, miniaturization and lightweight, and have obvious advantages in the fields of new energy vehicles, photovoltaic power generation, rail transit, smart grid and so on.  

Silicon carbide's advantages

Silicon carbide ceramics have the advantages of high pressure resistance, low creep at high temperature, and can adapt to various high temperature environments.  For example, silicon carbide beam, can be used in industrial furnaces bearing structure frame, its high temperature mechanical properties are excellent, long-term use does not bend deformation.  

Silicon carbide rod can be used for high temperature firing belt, it has good thermal conductivity, energy saving and does not increase the weight of kiln car.  

Silicon carbide cold air tube can be used in the cooling zone of the furnace, it has good cold and heat resistance, and its service life is 5~10 times that of stainless steel tube or alumina and other refractory materials.  

In addition, silicon carbide ceramics excellent resistance to high temperature and thermal shock performance, so silicon carbide is one of the main materials in rocket, aircraft, automobile engine and steam turbine thermal components.
