SiC ceramics not only have excellent mechanical properties at room temperature, such as high bending strength, excellent oxidation resistance, good corrosion resistance, high wear resistance and low friction coefficient, but also high temperature mechanical properties (strength, creep resistance, etc.) are the best known ceramic materials. Hot pressing sintering, non-pressing sintering, hot isostatic pressing sintering materials, its high temperature strength can be maintained to 1600℃, is the best high temperature strength of ceramic materials. The oxidation resistance is also the best of all non-oxide ceramics.

Silicon carbide (SiC) is a compound with strong covalent bonds, and the ionic type of its Si–C bond is only about 12%, so it also has excellent mechanical properties, excellent oxidation resistance, high wear resistance and low friction coefficient. The biggest feature of silicon carbide is high temperature strength, ordinary ceramic materials at 1200 ~ 1400 degrees Celsius strength will be significantly reduced, while silicon carbide at 1400 degrees Celsius bending strength is still maintained at a higher level of 500 ~600MPa, so its working temperature can reach 1600 ~ 1700 degrees Celsius. In addition, the thermal conductivity of silicon carbide ceramics is also high, second only to beryllium oxide ceramics in ceramics, so silicon carbide has been widely used in high temperature bearings, bulletproof plates, nozzles, high temperature corrosion resistant parts and high temperature and high frequency range of electronic equipment parts and other fields.

High Chemical Resistance High Temperature Strength Excellent Thermal Conductivity

The initial application of SiC is due to its super-hard properties, which can be prepared into various grinding wheels, emery cloth, sandpaper and various abrasive materials, so it is widely used in the machining industry. In the Second World War, it was found that it can also be used as a reducing agent and heating element in steelmaking, which promoted the rapid development of SiC. SiC ceramics in petroleum, chemical, microelectronics, automotive, aerospace, aviation, paper, laser, mining and atomic energy and other industrial fields have been widely used, silicon carbide has been widely used in high temperature bearings, bulletproof plates, nozzles, high temperature corrosion resistant parts and high temperature and high frequency range of electronic equipment parts and other fields.
