Abstract

The present invention provides a mixed conducting body, wherein it consists f 98 to 25 mol % of cubic or tetragonal zirconium dioxide, 1.5 to 25 mol % of an oxide stabilizing the zirconium dioxide phase and 0.5 to 50 mol % of at least one oxide of a metal of Group Va and VIa of the Periodic System of Elements and/or titanium dioxide, as well as the usual impurities. This body is outstandingly useful as electrode material for oxygen exchange reactions.
