ABSTRACT:
Process for applying a catalyst layer (4) composed of noble metals and/or noble-metal compounds to a ceramic carrier (1), in which process at least one ceramic intermediate layer (2) based on a glaze is applied, subjected to a heat treatment and cooled down. The catalyst layer (4) is in turn deposited as a chemical, electrochemical or physical deposit. Variants with .gamma.-Al.sub.2 O.sub.3 intermediate layer or with SiO.sub.2 intermediate layer or with Si intermediate layer.
