Silicon nitride ceramic ball is the high-precision ceramic material, sintered under high-temperature in non-oxide environment. It has special property to resist from acid, high-temperature, corrosion, and could be long time used inside sea water. It owns excellent electricity-resistant, magnetic-resistant property and almost have no change for strength and hardness even at 800℃. Its density is 3.20g/cm3, almost 1/3 weight of bearing steel.

Application Area: It can be applied as bearing ball, valve ball, measuring ball, track ball and fine grinding ball etc.

Application Area: As valve ball, it is widely applied for high-pressure homogenizer, pneumatic diaphragm pump, measuring pump, high-pressure spraying gun etc.
