Abstract

The effects of doping the mixed-conducting (La,Sr)FeO_3-δ system with Ce and Nb have been examined for the solid-solution series, La_{0.5_2x}Ce.rSr_0.5+xFeO_3-δ (x = 0-0.20) and La_0.5-2ySr_0.5+2yFe_1-yNb_yO_3-δ(y = 0.05-0.10). Mossbauer spectroscopy at 4.1 and 297 K showed that Ce⁴⁺ and Nb⁵⁺ incorporation suppresses delocalization of p-type electronic charge carriers, whilst oxygen nonstoichiometry of the Ce-containing materials increases. Similar behavior was observed for L_0.3Sr_0.7Fe_0.90Nb_0.10-δ at 923-1223 K by coulometric titration and thermogravimetry. High-temperature transport properties were studied with Faradaic efficiency (FE), oxygen-permeation, thermopower and total-conductivity measurements in the oxygen partial pressure range 10^-5-^0.5 atm. The hole conductivity is lower for the Ce- and Nb-containing perovskites, primarily as a result of the lower Fe⁴⁺ concentration. Both dopants decrease oxide-ion conductivity but the effect of Nb-doping on ionic transport is moderate and ion-transference numbers are higher with respect to the Nb-free parent phase, 2.2 x 10^∼3 for La_0.3Sr_0.7Fe_0.9Nb_0.1O_3-δcf. 1.3 x 10 for La_0.5Sr_0.5FeO_3-δ at 1223 K and atmospheric oxygen pressure. The average thermal expansion coefficients calculated from dilatometric data decrease on doping, varying in the range (19.0-21.2) x 10^-6K^-1 at 780-1080 K.
