Chemically and thermo-mechanically stable LSM-YSZ segmented oxygen permeable ceramic membrane
In this study, a dual phase oxygen permeable membrane based on a segmented structure of yttria stabilized zirconia (YSZ) and strontium-doped lanthanum manganite (LSM) was developed using a tape casting technique. Oxygen flux was significantly increased in the segmented membrane by a significant reduction in reactions between the YSZ and LSM. The segmented membrane also exhibited stable oxygen flux in the presence of both CO2 and H2O as well as against thermal stress. This chemically and thermo-mechanically stable YSZ based segmented membrane is proposed for real application in oxygen production. (C) 2015 Elsevier B.V. All rights reserved.
