Abstract

A dense membrane of perovskite Ba_0.5Sr_0.5Co_0.8Fe_0.2O_3-δ has been successfully prepared by polymerized complex method. Oxygen permeation according to carbon dioxide concentrations was measured in the oxygen partial pressure range of 2.1×10^-3∼0.63 atm and phase stability of membrane were examined using SEM-EDS. The oxygen flux increased with increasing temperature and pressure difference and the maximum oxygen permeation flux through 1.0 mm membrane was ca. 3.7 ml/cm²{dot operator}min at 950 ^{{ring operator}}C. The oxygen permeation in the condition of air and CO₂ (300∼700 ppm) in feed stream decreased more than 43% in comparison with air feed stream.
