Solid state electrotransport of oxygen in neodymium was studied. The effective valence Z* and the non-dimensional number δ (= uEL/D;u:mobility, E:electric field intensity, L:length of specimen, D:diffu-sion coefficient) of oxygen were measured by the tangent method under the following conditions;electric field intensity = 1.9∼2.5 Vm-1, temperature = 973∼1,223 K, initial oxygen content = 0.01∼0.11 mass %. The results can be summarized as follows: (i) The absolute values of the effective valence and δ of oxygen decrease with increasing either electric field intensity or temperature. (ii) The diffusion coefficient of oxygen in neodymium was determined as follows:DO /m2 s-1 = 0.26 exp (-196000/RT) (Nd(α):973 ∼ 1,073 K)DO /m2 s-1 = 1.6 × 10-2 exp (-180000/RT) (Nd(β):1,173 ∼ 1,223 K) (iii)Mobility of oxygen in neodymium increased with increasing temperature.
