Abstract
A method of manufacturing by magnetron cathode sputtering an electrolyte film for use in solid oxide cells (SOC). This method comprises the steps consisting of heating a substrate to a temperature ranging from 200° C. to 1200° C.; followed by subjecting the substrate to at least two treatment cycles, each treatment cycle comprising: 1) depositing one layer of a metal precursor on the substrate by magnetron cathode sputtering of a target made up of the metal precursor, the sputtering being carried out under elemental sputtering conditions; followed by 2) oxidation-crystallisation of the metal precursor forming the layer deposited on the substrate in the presence of oxygen to obtain the transformation of the metal precursor into the electrolyte material; and in that the substrate is kept at a temperature ranging from 200° C. to 1200° C. for the entire duration of each treatment cycle.
