                      perovskites are promising materials for oxygen separation
                      membranes at high temperatures. Gaslight 10-20 mu m-thick
                      perovskite layers were produced by vacuum slip-casting and
                      screen printing on different porous substrates, i.e.
                      Ce0.8Gd0.2O1.9 (CGO), LSFC and composites of both. Some of
                      the substrates are doped with cobalt for enhancing the
                      mechanical stability and the shrinkage rate of the
                      substrate. The manufacturing of the substrates and the
                      different perovskitic asymmetric membranes are described in
                      detail. The microstructure, the chemical compatibility
                      between substrate and membrane, and the stability of the
                      sintered layers were analyzed by scanning electron
                      microscopy (SEM, EDX), SIMS and XRD at room temperature.
                      Also the shrinking rates, surface smoothness, porosity and
                      air permeance of the different substrate compositions are
                      characterized. SEM analysis of the sintered top-layers
                      showed a thickness of 10-20 mu m, only closed porosity after
                      sintering at 1200 degrees C and an He-leak rate in the range
                      between 10(-4) to 10(-6) mbar l s(-1) cm(-2). The thermal
                      expansion coefficient and electrical conductivity of the
                      membrane materials and the substrates are measured between
                      30 and 800 degrees C and oxygen flux measurements were
                      carried out in the range 750-900 degrees C. (c) 2006
