abstract = {Powders of constant morphology and quality are
indispensable for reproducible ceramic manufacturing. 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.},
