Abstract
Method of applying a catalyst layer consisting of precious metals and/or precious metal compounds to a substrate of ceramic material by an electrically conducting SnO.sub.2 intermediate layer, doped with Sb, being pyrolytically applied to the surface of the substrate and subjected to an additional heat treatment for the purpose of consolidation and sintering, whereupon the catalyst layer is applied electrolytically to the intermediate layer.
