Resumo
Zirconia–10 mol% scandia–1 mol% dysprosia solid solution was prepared by the coprecipitation method assisted by spark plasma sintering aiming to verify the densification and the electrical conductivity of the solid electrolyte. Full stabilization of the cubic phase at room temperature was evidenced by room temperature X-ray diffraction. The consolidation technique allowed for obtaining high relative density (> 97% of the theoretical value) specimens at low temperatures (1100–1300 °C) with average grain sizes in the submicrometer–micrometer range depending on the sintering temperature. The average grain size is 4.76 μm after consolidation at 1300 °C for 4 min. The total electrical conductivity reached 3.6 mS⋅cm− 1 at 650 °C.
