Interaction of Copper Oxide with Zirconium Dioxide Stabilized with Yttrium Oxide

Resumo

The effect of adding copper oxide in an amount of 0.9 wt.% on sintering capacity, microstructure, and phase composition of material based on zirconium dioxide stabilized with yttrium oxide is studied. Powder is prepared by reverse precipitation with ammonia from aqueous solutions. It is shown that in the presence of copper oxide there is formation of monoclinic zirconium dioxide, appearance of a liquid phase in the range 1120 – 1200°C, and a change in material color and porosity.
