Abstract
Abstract Commercial powders within the system ZrO 2 -MgO-Y 2 O 3 -Al 2 O 3 were used to produce zirconia ceramics with improved thermal stability. Different sintering routes were followed in order to determine the optimum conditions. Fine-grained (Y, Mg)-PSZ ceramics with grain sizes below 10 μm were achieved. Microstructural evolution was studied after various isothermal heat treatments. After ageing, the materials contain a large fraction of tetragonal phase which does not transform after a hydrothermal ageing treatment in an autoclave, but can still be transformed under mechanical stress.
