Four Main Applications Of Silicon Nitride Ceramics
1. Application of silicon nitride ceramics in the mechanical field Silicon nitride ceramics are used in the machinery industry as valves, pipes, classifying wheels, and ceramic cutting tools. The most common use is silicon nitride ceramic bearing balls. Compared with steel balls, silicon nitride ceramic bearing balls have outstanding advantages: low density, high temperature resistance, self-lubricating, and corrosion resistance. They are used in high-speed machine tool electric spindle high-speed bearings, aerospace engines, wind turbine bearings, and automobile engine bearings. Bearings for equipment such as As a high-speed rotating body, the ceramic ball generates centrifugal stress, and the low density of silicon nitride reduces the centrifugal stress on the outer ring of the high-speed rotating body. 2. Application of silicon nitride ceramics in the semiconductor field In addition to superior mechanical properties, silicon nitride ceramics also exhibit a range of excel...
