Ba and Srβ-alumina ionic conductors were synthesized by solid state sintering at 2033 to 2073 K and their electrical conductivities were measured by a.c. impedance spectroscopy. The electrical conductivities at 1673 K were 2.05×10-2 and 4.6×10-3 S m-1 for Sr and Baβ-aluminas, respectively. An oxygen concentration cell and d.c. polarization methods were applied to measure the ionic transference numbers. The values obtained by the two methods were almost in agreement at more than 1400 and 1673 K for Srβ-alumina and Baβ-alumina, respectively. Srβ-alumina could have slightly greater ionic transference numbers than Baβ-alumina.
