Silicon Carbide Ceramics:
SiC ceramics not only have excellent mechanical properties at room temperature, such as high flexural 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 among known ceramic materials.
The high temperature strength of hot press sintering, pressureless sintering and hot isostatic pressing sintering materials can be maintained to 1600 °C, which is the best material with high temperature strength among ceramic materials.
The oxidation resistance is also the best of all non-oxide ceramics. Also known as emery.
Application:
The initial application of SiC is due to its superhard properties, which can be prepared into various grinding wheels, emery cloths, sandpaper and various abrasives, so it is widely used in the machining industry. In World War II.
It was also found that it could also be used as a reducing agent and heating element in steelmaking, thus promoting the rapid development of SiC.
SiC ceramics have been widely used in petroleum, chemical, microelectronics, automotive, aerospace, aviation, papermaking, laser, mining and atomic energy and other industrial fields.
Silicon carbide has been widely used in high-temperature bearings, bulletproof plates, nozzles, high-temperature corrosion-resistant parts and high-temperature and high-frequency electronic equipment components and other fields.
