Ternary ZrO2-CeO2-Y2O3 ceramics were prepared by the mechanical mixing of commercial ZrO2-CeO2 and ZrO2-Y2O3 powders. The microstructure and phase ratios of the compositions sintered within the two-phase tetragonal plus cubic region were determined. The ionic conductivities of the samples were determined and the influence of microstructure on the bulk conductivity was studied. The effect of ceria and yttria additions on ionic conductivity was investigated, along with crystal structure and the microstructure for series where the concentration of each of the dopants was kept unchanged.
