Instead of using Ti in the samples, 10–15 mol%Al was used, resulting in lattice contraction in the c-axis direction. The samples, sintered at 500–800°C for 12 h by a reaction sintering method, had a relative density of 70–80% and their grain size was 2–3 µm. The ionic conductivity calculated from the grain and grain boundary resistance at 600°C was 7.1 × 10<sup>−5</sup> and 1.3 × 10<sup>−5</sup> S/cm, respectively. The activation energy of the grain conductivity was 128 kJ/mol in the temperature range of 300 to 600°C.
