Ceramic balls could be separated into two types: non-oxide ceramic balls (such as silicon nitride, Si3N4 balls) and oxide ceramic balls (such as alumina and zirconia balls). Weight of a Si3N4 ceramic ball is less than half weight of a general steel ball. Besides, ceramic balls have excellent performance of corrosion resistance, antirust, wear resistance, high working temperature, electrical insulation etc. Thus, these balls are using in aerospace, high precision bearings, wind power generation, pumps, valves etc.
