Abstract

Oxide ion conductivity of Ga based perovskite type oxides, LnGaO₃ (Ln = Nd, La) and its related oxide, A₃Ga₂O₆ (A = Ba and St) was investigated. Oxide ion transference number is almost 1.0 on Sr₃Ga₂O₆ or Ba₃Ga₂O₆. However, electrical conductivity of these A₃Ga₂O₆ system oxides was lower than log (σ/S cm^-1) = - 3 due to the low solubility of the aliovalent cations. On the other hand, doped perovskite type oxide of NdGaO₃ and LaGaO₃ exhibited a high electrical conductivity and the transference number of oxide ion was higher than 0.9 in the oxygen partial pressure range from PO₂ = 1 to 10^-21 atm. In particular, Ca and Mg doped NdGaO₃ exhibited a high oxide ion conductivity in similar with LaGaO₃ based oxide.
