abstract = {Ce0.8Gd0.2O2-δ-FeCo2O4 membranes, benefiting from their
excellent chemical stability, exhibit a broad application
potential in oxygen-consuming industrial processes running
in harsh environments. For long-term reliable operation, the
membrane needs to possess sufficient mechanical strength.
This paper characterizes the typical aspects that challenge
the mechanical stability of the sintered membrane, including
composition and microstructural defects as well as residual
stress and residual stress gradients. It is revealed that
mechanical strengths of the sintered membranes increase with
decreasing iron cobalt spinel content, that the high iron
cobalt spinel content induces microcracks, and that high
residual tensile stress gradually decreases from the
as-sintered surface to the bulk. Although the residual
tensile stress can be reduced by applying an extensive
elevated temperature dwell time during cooling, it is
suggested to limit the iron cobalt spinel content to a
nominal value of 15 $wt\%$ to eliminate the residual tensile
stress while maintaining a high mechanical strength.},
