Abstract

Die Erfindung betrifft eine Sauerstoffmembran umfassend ein oxidsches Material, welches einen Sauerstoffdiffu­sionskoeffizienten von mindestens 10-4 cm2 s-1 und eine K2NiF4-Schichtstruktur aufweist, bei der wenigstens eine Perowskitschicht an eine weitere Schicht angrenzt, die keine Perowskitstruktur aufweist. Dieses oxidische Material weist eine besonders gute Sauerstoffleitung, insbesondere im Temperaturbereich von 800 bis 1000 °C auf, und ist damit besonders für den Einsatz in einer Sauerstoffmembran geeignet, welche bei hohen Arbeitstemperaturen beispielsweise in einem Katalysereaktor eingesetzt wird.
