Zirconia ceramic ball (ZrO2)
Zirconia ceramic balls have high strength, high toughness, good wear resistance, high temperature and corrosion resistance, high rigidity, non-magnetic conductivity and electrical insulation at room temperature. At 600 ℃, the strength and hardness of zirconia ceramic ball are almost unchanged. Its density is 6.00g/cm3, and its thermal expansion rate is close to that of metal. If the expansion rate is close to that of metal, it can be used in conjunction with metal.
Characteristics of zirconia ceramic balls:
1. zirconia ceramics are self-lubricating, which can solve the pollution and inconvenience caused by lubricating medium; Good corrosion resistance, it can also be used in medium acid, medium alkali, seawater and other media; High temperature resistance, the strength and hardness of zirconia ceramics are almost unchanged at 600 ℃; It is non-magnetic, insulating, and can also be used in a magnetic field. It is non-conductive.
2. applicable fields: semiconductor, LCD manufacturing equipment, electroplating equipment, synthetic fiber manufacturing equipment, optical film equipment, various heat treatment furnaces, vacuum equipment, etc; It can also be used in composite bearings, cold working tools, various guide wheels, various valves, vacuum equipment and various harsh environments.
