Abstract: A method for producing a solid electrolyte layer, of a fully stabilized zirconium oxide layer on a substrate includes adding a sintering additive to a ZrO2-starting material, a liquid phase is formed during a sintering process and liquid phase sintering is possible at a reduced temperature in comparison with the required sintering temperature without the sintering additive. The reduced sintering temperature substantially prevents the formation of a foreign phase layer between the substrate and the gas-tight layer applied thereon, being of fully stabilized ZrO2. The method is particularly suitable for producing a solid electrolyte layer on a cathode of a high temperature fuel cell and in a sensor.
