- Abstract
- The present article is devoted to the study of the stability of microtubular membranes based on Ba0.5Sr0.5Co0.8 – xFe0.2MoxO3 – δ oxides obtained by the phase inversion method. The work shows that MT membranes of the composition BSCFMx exhibit long-term stability and resistance to thermal cycling in an air/helium gradient. The maximum oxygen fluxes were achieved using an MT membrane of composition Ba0.5Sr0.5Co0.75Fe0.2Mo0.05O3 – δ (JO2 =7.6 ml*cm-2min-1 at Т=850 oС and pO2.1 = 0.21 atm). In this work, a detailed equilibrium phase diagram for the BSCFM5 oxide has been obtained. The absence of unwanted phase transitions has been demonstrated.
