Effect of copper oxide on the polymorphism of unstabilized and yttria-stabilized zirconia
We have studied the effect of copper oxide doping on the phase composition of unstabilized and yttria partially and fully stabilized zirconia prepared via hydroxide precipitation followed by heat treatment at different temperatures. Copper oxide is shown to stabilize cubic zirconia only in the presence of yttria. The chemical processes in the CuO-Y2O3-ZrO 2 system and the mechanisms of C-ZrO2 stabilization are discussed.
