Applications:
Silicon nitride ceramics (SI3N4 ceramic ball) are widely used in many different applications and scenes due to their high bending strength (750 MPa), low poisson's ratio (0.25-0.3), dielectric strength (18-20 KV/mm), elastic modulus (290 GPa) and place of origin (China).
For example, SI3N4 ceramics balls can be used as bearings, which require low noise, low vibration, and high temperature resistance. In addition, SI3N4 ceramics can also be used in medical fields, such as artificial hips and artificial knee joints, due to its excellent shock resistance. Furthermore, silicon nitride ceramics can be used for electrical insulation parts since it has high dielectric strength. In addition, silicon nitride ceramics are also widely used in the automotive industry, such as brake discs, engine components, and transmission components, due to its high strength and excellent wear resistance. Finally, silicon nitride ceramics are also used in the aerospace industry, such as fuel nozzles, turbine blades, and other high-temperature components.
