Abstract (en)
[origin: WO0216669A1] According to the inventive method, a sintering additive (4) is added to a ZrO2-starting material (2), 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 (4). The reduced sintering temperature substantially prevents the formation of a foreign phase layer between a substrate (10) and the gas-tight layer (12) applied thereon, consisting of fully stabilized ZrO2. The inventive method is particularly suitable for producing a solid electrolyte layer (14) on a cathode (16) of a high temperature fuel cell (18).
