In this study, commercially available powders were characterized regarding their microstructural properties and screened for a reproducible membrane manufacturing process, which was done by sequential tape casting. Basing on this, the slurry composition and ratio of ingredients were systematically varied in order to obtain flat, crack-free green tapes suitable for upscaling of the manufacturing process. Debinding and sintering parameters were adjusted to obtain defect-free membranes with diminished bending. The crucial parameters are the heating ramp, sintering temperature, and dwell time. The microstructure of the asymmetric membranes was investigated, leading to a support porosity of approximately $35\%$ and a membrane layer thickness of around 20 µm. Microstructure and oxygen flux are comparable to asymmetric La0.6Sr0.4Co0.2Fe0.8O3-δ (LSCF) membranes manufactured from custom-made powder, showing an oxygen flux of > 1 mLcm−2min at 900 °C in air/Ar gradient.}, cin = {IEK-1}, ddc = {600}, cid = {I:(DE-Juel1)IEK-1-20101013}, pnm = {113 - Methods and Concepts for Material Development (POF3-113) / GREEN-CC - Graded Membranes for Energy Efficient New Generation Carbon Capture Process (608524)}, pid = {G:(DE-HGF)POF3-113 / G:(EU-Grant)608524}, typ = {PUB:(DE-HGF)16}, pubmed = {pmid:32019115}, UT = {WOS:000515503100121}, doi = {10.3390/ma13030614}, url = {https://juser.fz-juelich.de/record/873402}, }
