Abstract

To provide a substrate enclosed in a uniform nucleation layer, a substrate is nucleated with a noble metal salt where the noble metal salt is chemically bound to the substrate, and a method is described for binding a noble metal salt chemically to a substrate. To provide a metal plated powder, a powder is nucleated with a noble metal salt and the nucleation is coated with a metal layer. A method is also provided for nucleating the powder surface with a noble metal salt in such a manner that it is chemically bound to the substrate and then metal plated by a conventional electroless method.
