Abstract

Dense tubular membranes were produced by centrifugal casting of an aqueous suspension, containing powder particles of the mixed-conducting perovskite La0.5Sr0.5CoO3−δ and a dispersant. The resulting green bodies were dried and sintered to produce tubes with a maximum length of 12 cm, having a relative density higher than 92%. The particle morphology, the amount of dispersant and its burnout appeared to influence the quality of the final product. Oxygen permeation measurements were conducted in the temperature range 850°–950°C in Air/He gradients. Results were found to be consistent with data reported for disk-type membranes.
