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}, cin = {IEK-1}, ddc = {670}, cid = {I:(DE-Juel1)IEK-1-20101013}, pnm = {113 - Methods and Concepts for Material Development (POF3-113)}, pid = {G:(DE-HGF)POF3-113}, typ = {PUB:(DE-HGF)16}, UT = {WOS:000374328500003}, doi = {10.1007/s11666-016-0383-y}, url = {https://juser.fz-juelich.de/record/810170}, }
