- Abstract
The kinetics of oxygen exchange in the nonstoichiometric strontium ferrite SrFeO with the structure of cubic perovskite was studied by the oxygen partial pressure relaxation technique in the isostoichiometric regime at temperatures of 500-900°C in a range of δ from 0.24 to 0.44. An increase in the oxygen nonstoichiometry δ was accompanied by a decrease in the rate of sample relaxation and by an increase in the apparent activation energy of oxygen exchange.
