英文摘要	Weakly agglomerated nano-crystalline Ho2O3 and Sc2O3 stabilized ZrO2 (HoScSZ) powders are prepared by the hydrothermal method. Dense HoScSZ ceramic pellets are fabricated by isostatically pressing the powders then sintering at 1350 degrees C for 2 h. All the HoScSZ samples are cubic phase verified by X-ray diffraction. 7 mol % Sc2O3 + 1 mol % Ho2O3 stabilized zirconia (7Sc1HoSZ) is verified by impedance spectroscopy possessing the higher conductivity than that of 8 mol % Sc2O3 stabilized zirconia (8ScSZ). Space charge potential and specific grain boundary conductivity are calculated and fitted under the circumstance that the grain boundary is free of any amorphous phase which is verified by high resolution transmission electron microscopy. With the increase of the doping content of Ho2O3, the specific grain boundary conductivity and space charge potential decrease, while oxygen vacancy concentration increases.
