Brief Introduction of Zirconia Ceramic Balls

Mar 10, 2017


Zirconia ceramic ball has the performance of high strength, high toughness, high wear resistance, high temperature resistance, corrosion resistance, high rigidity, non-magnetic and electrical insulation at room temperature. At 600 ℃, the strength and hardness of zirconia ceramic ball is almost constant. Its density is 6.00g / cm3, whose weight is 77% weight of a general steel ball. The thermal expansion of zirconia ball is close to the metal thermal expansion and can be used in conjunction with metal. As its self-lubricating, it can solve the pollution caused by lubricating media and adding inconvenience. Therefore, zirconia ball is usually used in pumps, valves, ceramic bearings and so on.
