Abstract
PURPOSE:To obtain the titled part having excellent abrasion resistance at a reasonable price, by heat-treating a mixture containing ZrO2, CeO2, Y2O3 and oxide of a lanthanide group element and using the obtained solid solution as a component. CONSTITUTION:The objective part contains >=80wt.% of a zirconia solid solution produced by the heat-treatment of a mixture containing 80.5-96.5wt.% of ZrO2, 2.5-11.0wt.% of CeO2, 0.6-5.0wt.% of Y2O3 and 0.1-3.5wt.% of an oxide of a lanthanide group element having atomic number of 59-71. The oxide of the lanthanide group element having an atomic number of 59-71 is e.g. Gd2O3, Nd2O3, Pr2O3, Sm2O3, Dy2O3, Yb2O3 or Er2O3 and the oxide is used singly or in combination of two or more kinds of oxides. The part for crusher made of zirconia ceramic has a Vickers hardness of >=1,100. Preferably <=30wt.% of the crystal of zirconia is monoclinic to obtain a part having high hardness and excellent abrasion resistance.
