Abstract

3 mol% Y2O3-doped ZrO2 powders were prepared by hydrolysis with 0.1, 0.2, 0.3, 0.4, 0.5, 0.6 mol/ιH2O/ethanol into 0.1 mol/ι zirconium and yttrium alkoside/ethanol. Spherical monodispersed yttria-partially stabilized zirconia particles with an average diameter of about 0.5 ${\mu}{\textrm}{m}$ were prepared by hydrolysis with 0.2 mol/ιH2O/ethanol. The as-prepared powder was amorphous and with heating it transformed into cubic up to 80$0^{\circ}C$ and into tetragonal over 100$0^{\circ}C$. 3 mol% Y2O3-doped ZrO2 powders calcined over and up to 80$0^{\circ}C$ were a mixture of tetragonal and monoclinic and only tetragonal as determined by X-ray diffraction, respectively.
