摘要：
Asymmetric dual-phase membranes with a composition of 75 wt% Ce0.85Sm0.15O2-delta-25 wt% Sm0.6Sr0.4Al0.3Fe0.7O3-delta (SDC-SSAF) were prepared by tape-casting and co-lamination technique. The membrane has a thin dense layer of similar to 40 mu m and a porous support of similar to 460 mu m. It demonstrated an oxygen permeation flux as high as 3.9 mL cm(-2) min(-1) at 950 degrees C. This high value is commercially attractive for pure oxygen production via asymmetric dual-phase membranes. (C) 2015 Elsevier B.V. All rights reserved.
