Abstract
Yttria-stabilized zirconia (YSZ) co-doped with trivalent oxide Sc2O3 and Yb2O3 is prepared using mechanical alloying and high-temperature sintering. High-temperature XRD analysis was performed to study the phase transformation and lattice parameter changes of various phases in the baseline YSZ and co-doped samples. The results show that the structure for the co-doped samples tends to be more thermally stable at test temperature above critical value. The lattice parameters for all samples increase with temperature at which XRD is carried out, and the lattice parameters for the two trivalent rare earth oxides co-doped YSZ are smaller than that for 7YSZ under the same temperature.
