ABSTRACT:
A method for preparing a ceramic article comprising compacting a particulate alloy of a primary oxide and a secondary oxide to form a blank, and sintering the blank in contact with substantially pure zirconium oxide. The primary oxide is zirconium oxide and the secondary oxide is selected from the group consisting of MgO, CaO, Y.sub.2 O.sub.3, Sc.sub.2 O.sub.3, rare earth oxides and combinations thereof. Ceramic articles produced have tetragonal phase cores and monoclinic cases.
