  • functional materials;
  • ageing effect in zirconia-based electrolytes;
  • interpretation


The electrical conductivity and the crystal structure of specimens with 8 mol% and 10 mol% yttria were determined before and after annealing at 1000°C. Scandia-stabilised zirconia electrolytes (ScSZ) were investigated too, with an scandia content varying from 7 mol% to 13 mol%. Like for YSZ electrolytes, the electrical conductivity was measured and crystal structure was determined before and after annealing. Mechanical spectroscopy was performed on this system. Then, the electrical data and the structure analyses of both systems are correlated to each other and discussed. Finally, according to the literature and to the presented results, an interpretation is given for the ageing effect for all the zirconia-based electrolytes.
