abstract = {La0.58Sr0.4Co0.2Fe0.8O3− δ (LSCF) deposited on a
metallic porous support by plasma spray-physical vapor
deposition is a promising candidate for oxygen-permeation
membranes. Ionic transport properties are regarded to depend
on the fraction of perovskite phase present in the membrane.
However, during processing, the LSCF powder decomposes into
perovskite and secondary phases. In order to improve the
ionic transport properties of the membranes, spraying was
carried out at different oxygen partial pressures p(O2). It
was found that coatings deposited at lower and higher oxygen
partial pressures consist of $70\%$ $cubic/26\%$
rhombohedral and $61\%$ $cubic/35\%$ rhombohedral perovskite
phases, respectively. During annealing, the formation of
non-perovskite phases is driven by oxygen non-stoichiometry.
The amount of oxygen added during spraying can be used to
increase the perovskite phase fraction and suppress the
formation of non-perovskite phases},
