Abstract
Electrical conductivity relaxation (ECR) experiments were carried out on La0.6Sr0.4Fe0.8Co0.2O3−δ (LSFCO) in the temperature range of 840 to 910 °C and in the oxygen partial pressure range of 0.01 to 0.05 atm. The effects of annealing at 900 °C on the oxygen transport properties were investigated for individual samples. The values of DO2−=D̃O/ΓO and kex=kchem/ΓO agree well with the result from isotope-exchange depth profile (IEDP) experiments.
