An engineering ceramic which is useful for producing long life components for internal combustion engines. It comprises a partially stabilised zirconia ceramic alloy having a transformable tetragonal phase, wherein the stabiliser is selected from magnesium oxide, calcium oxide and indium sesquioxide, and mixtures thereof. The ceramic alloy is prepared by sintering the mixture of oxides in the cubic solid solution region followed by controlled cooling and heat treatment. |
