摘要：
We have studied oxygen release from a membrane material with the composition SrCo0.8Fe0.2O3 - delta of various sizes in the temperature range 600-900A degrees C in a flow reactor at oxygen partial pressures from 0.2 to 10(-5) atm. The results demonstrate that the oxygen release from samples 50 mu m to 2 mm in size at temperatures above 800A degrees C can be described in terms of a quasi-equilibrium model. For fine powders, a parts per thousand currency sign63 mu m in size, the temperature range of quasi-equilibrium oxygen release begins at t a parts per thousand yen 600A degrees C.
