Zirconia ceramic balls have high strength and toughness at room temperature, good wear resistance, high temperature corrosion resistance, high stiffness, non-magnetic conductivity, and electrical insulation. At 600 ℃, the strength and hardness of zirconia ceramic balls are almost unchanged, and the density is 6.00g/cm3, and the thermal expansion rate is close to the thermal expansion rate of metal, so it can be used in conjunction with metal. For bearings, seals, etc.
