Oxide ion conductivity in doped Ga based perovskite type oxide

Oxide ion conductivity of Ga based perovskite type oxides, LnGaO, (Ln = Nd, La) and its related oxide, A,Ga,O, (A = Ba and St) was investigated. Oxide ion transference number is almost I.0 on Sr,Ga,O, or Ba,Ga,O,. However, electrical conductivity of these A,Ga,O, system oxides was lower than log (...
