N2 - 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.
