Lanthanum based perovskite oxides are subject of extensive studies for application as oxygen-separation membranes where they are designed to be used as tubes in advanced reactors. In the present study, tubular La 0.2Sr 0.8Fe 0.8Cr 0.2O 3− δ perovskite membrane has been evaluated for structural prope...
