SOL AND METHOD FOR PRODUCING A DELAFOSSITE MIXED OXIDE LAYER STRUCTURE ON A SUBSTRATE AND ALSO A SUBSTRATE COATED WITH A MIXED OXIDE

摘要

The present invention relates to a sedimentation-stable sol which, in addition to a copper(II) salt, also comprises at least one further metallic salt, an additive which is contained ensuring that the metallic salts contained in the sol remain dissolved or in dispersion. Furthermore, the sol is suitable in the method according to the invention for producing a metallic mixed oxide layer on a substrate, the metallic mixed oxide layer having a delafossite structure. Likewise, a substrate which has a metallic mixed oxide layer with a delafossite structure and also possibilities of use thereof are indicated according to the invention.
