This suspension contains an inorganic acid which hardly dissolves the substrate material and dissolves the added noble metal salt partially or wholly. A reducing agent need not be more than it can reduce a noble metal salt and its ions, but hydrozine in a particularly preferable reducing agent. Said preparation gives substrate material powder coated with a high-purity noble metal.
