Abstract: 

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. The comparative analysis was performed based on the following parameters: inner and outer diameter, shrinkage, and the dimensions of the gas-tight and porous layers.

Key words:
