ABSTRACT:
A method for preparing a ceramic article comprising compacting a particulate including a primary oxide and a secondary oxide to form a blank. The primary oxide is ZRO.sub.2 and the secondary oxide is MgO, CaO, Y.sub.2 O.sub.3, Sc.sub.2 O.sub.3, rare earth oxides or a combination thereof. The blank is sintered in contact with MgO, CaO, Y.sub.2 O.sub.3, Sc.sub.2 O.sub.3, rare earth oxides or a combination thereof. The zirconia alloy ceramic articles produced have a cubic phase case and a tetragonal phase core.
