摘要：
The effect of the chemical composition of some perovskite-like cuprates, manganites, and cobaltite on their reactivity for oxygen and water vapor that are present in the annealing atmosphere, at 200–400°C has been studied. The partial substitution and alloying of LnBa2Cu3Oy compounds lead to the increase in their stability with respect to aggressive components of gas phase (H2O, CO2). It was found that only compounds with structures characterized by several kinds of oxygen vacancies can absorb oxygen and water from the annealing atmosphere.
