Silicon nitride ceramic has high hardness, excellent acid and alkali corrosion resistance, and self-lubricating. Therefore, silicon nitride ceramic balls can be used as bearing balls with metal or bushings of the same material. Its own advantages Can be used in special environments;

In addition, it can be used as a ceramic valve ball in the oil field, and its electrical insulation can also be made into an insulating ring; and because of its high sintering temperature, it can be operated at high temperatures, so silicon nitride structural parts can be used as high-temperature support materials. High-tech fields; silicon nitride ceramic knives are used in industrial machine tools, etc.
