    • Abstract

       

      Oxygen-selective membranes based on thin layers of barium–strontium–cobalt ferrite Ba$_{0.5}Sr$_{0.5}$Co$_{0.8}$Fe$_{0.2}O$_{3−\delta}$ (BSCF) perovskite oxide were manufactured. Five BSCF inks prepared with differentcarriers and milling treatments were rheologically characterized, screen printed on three different porous alumina substrates and sintered at 1050 and 1150$^{\circ}$C. The resulting membranes were characterized. The data collected on the rheological properties of inks (flow curves, thixotropic behaviour, linear viscoelasticity), their processability by screen printing, and the quality of the layers obtained after sintering represents an important starting point to set up the next research activities.
