Microtubular membranes with the composition of La0.6Sr0.2Ba0.2Fe0.7Ni0.1Co0.2O3−δ were fabricated using phase inversion and dip- coating methods, followed by sintering in air. The obtained microtubular membranes were characterized by X-ray diffraction analysis and scanning electron microscopy. The optimal sintering temperature was selected taking into account the target application of the microtubular membranes and the corresponding microstructural requirements.
