Abstract
A serial of Ba0.8Sr0.2Fe0.5Co0.5O3-δoxides were prepared by the citrate method and sintered at different temperatures from 400°C to 900°C. The mass loss of various samples with elevated temperature was characterized by TGA analysis. The results indicated that several kinds of compositions lost from the samples in the elevated temperature process. The oxygen adsorption capacity of these samples over a temperature range of 200-900°C were calculated by the data of TGA experiment. The sample sintered at 400°C exhibited the best oxygen sorption ability.
