Brief Introduction of Zirconia Ceramic Balls


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.
