Oxygen Separator Based on SrCo<sub>0.8</sub>Fe<sub>0.1</sub>Sn<sub>0.1</sub>O<sub>3-δ</sub> Permeable Membranes

In this article, the densely SrCo0.8Fe0.1Sn0.1O3-δ (SSCF) tubular membranes were prepared by the traditional extrusion method. The prototype oxygen separator was constructed by the resulting SSCF tubular membrane. The resulting oxygen product had purity over 99%. At 920oC, a tubular membrane with a wall thickness of 1.4mm, had the permeation rate of 2.4ml/min.cm2, which kept unchanged during 1000hrs operation.
