We all realize that with the fast developing of industry, the conventional steel shafts are not appropriate choices for high speed rotation applications use any more, due to their high rotational inertia. So zirconia was introduced for shaft use for their outstanding properties. Zirconia material is one of the oldest oxide ceramic materials, it is refined with special stabilizers into a completely new material with high performances for good strength, wear resistance, corrosion resistance, working stable at high temperature. So after zirconia was introduced for steel shafts replacement and achieved significant success in recent years. Yttria stabilized zirconia shafts can effectively reduce the high speed rotational centrifugal force and inertial force. Additional zirconia has much more excellent characteristics for high hardness, self lubricating, high temperature resistance and high chemical resistance, so zirconia shafts are becoming good replacements for high performance pumps use.
