Реферат: High-temperature studies of the structure of a composite material with the composition La0.6Sr0.4Co0.2Fe0.8O3-δ-Ce0.8Sm0.2O2-δ (LSCF64-SDC) have been carried out, and the oxygen permeability of microtubular membranes based on it was investigated. The phase composition of LSCF64-SDC composite was analysed using in situ high-temperature X-ray diffraction. It has been determined that at 700 °C under vacuum conditions, a structural transition to the high-temperature cubic phase occurs in LSCF64 oxide. The dependence of the oxygen permeability of microtubular membranes based on LSCF64-SDC on the partial pressure of oxygen and temperature has been established. The effective activation energy of the oxygen transport process was calculated. The effect of the CO2 atmosphere on the values of oxygen flows through the microtubular membranes based on LSCF64-SDC was studied.
