Scandia-stabilized zirconia (ScSZ) electrolytes exhibit the highest ionic conductivity among all ZrO2-based materials. However, a phase transition occurs around 650 degrees C from cubic to rhombohedral beta-phase which is unique for Sc-stabilized zirconia and leads to reduced conductivity. The occurrence of this beta-phase can be suppressed by co-doping ScSZ. The aims of this study are to confirm the influence of a small amount of Fe2O3 doping on both the stabilization of the cubic phase and the decrease of the sintering temperature and to investigate the influence of this co-doping on the ionic and electronic conductivity of ScSZ. Therefore (ZrO2)(0.90)-(Sc2O3)(0.07)-(Fe2O3)(0.03) powder has been prepared by precipitation in aqueous solution and sintered at 1380 degrees C to obtain ceramic. The electrical properties (ionic and electronic conductivities) of this ceramic are compared to the ones of Fe-doped YSZ. (C) 2013 Elsevier B.V. All rights reserved.
