Nanopowders with nominal constant oxygen vacancy concentrations of 8, 10, and 12 mol % were prepared in the ternary ZrO2-CaO-Y2O3 system. The constant oxygen vacancy concentrations were obtained by incorporating calcia and yttria into zirconia solid solutions at different ratios. The Rietveld refinement method was used to characterise the structural changes in the zirconia solid solution. X-ray diffraction analysis was also used to characterise the phase composition of the samples and lattice parameters of the cubic phase. The four-probe method was applied for determining electrical properties of the samples. The conduction properties of the samples were characterised with respect to their structural features.
