Abstract (en)
[origin: WO2017129209A1] The invention relates to a method for producing a ceramic cathode layer on an electrically conducting substrate, in which first a coating in the form of a suspension, comprising at least one suspending agent and at least one ceramic material, is applied to this electrically conducting substrate. This is followed by heating the coating in a reducing atmosphere such that the ceramic material is fully or partially reduced to a fusible reaction product. After that, the coating is heated in a reducing atmosphere to temperatures above the melting point of the reaction product, thereby forming a molten substance. This is followed by densifying or sintering of the coating in a reducing atmosphere at temperatures that lie 100°C above the melting temperature of the reaction product. A reoxidation of the densified or sintered coating subsequently takes place in an oxidizing atmosphere in a temperature range between 400 and 1200°C, wherein the reaction product is oxidized again and reacts again into the original composition of the ceramic material used.
