Method of chemically metal coating bad-electroconductive supporter comprising inorganic material

Abstract

Abstract Process for chemically metallizing an inorganic substrate, which is a poor conductor of electricity, e.g. a ceramic material or glass. The surface of the substrate is chemically activated so that chemical bonds are more readily formed with a subsequently applied, inorganic adhesion promoter. The adhesion promoter in turn facilitates chemical bonding with a subseqently applied metal layer, e.g. a copper layer, which is applied by a wet chemical method. The activation step and the step of applying an adhesion promoter, in combination with at least one thermal treatment, results in an adhesive strength between the metal layer and the substrate surface which equals or exceeds the adhesion strength of the surface of the substrate material.
