VERFAHREN ZUR METALLBESCHICHTUNG VON ANORGANISCHEN PARTIKELN MITTELS STROMLOSER METALLABSCHEIDUNG
The invention relates to a process for producing metal-coated inorganic particles by means of currentless deposition technique in which the inorganic particles are first functionalized, then introduced into an aqueous metal-salt solution containing metal ions, and the metal is reduced by adding a reducing agent to the aqueous metal-salt mixture containing the functionalized particles and the metal is deposited on the functionalized particles, wherein the functionalization of the inorganic particles takes place by means of aminophosphonic acids, aminocarboxylic acids and/or aminoalcohol phosphoric acid esters, and the aminophosphonic acid, the aminocarboxylic acid and/or the aminoalcohol phosphoric acid ester form(s) a monolayer on the surface of the inorganic particles. The metal-coated inorganic particles can be introduced into metal matrices due to their improved surface properties.
