Abstract
Composite powder coated with a noble metal is produced by adding a powder of a metal or alloy baser than the noble metal to a powder of a metallic sulfide, carbon, activated charcoal, metallic carbide, or metallic oxide, and then adding to the resulting mixture a solution containing the noble metal with stirring. The particles of the composite powder are coated with the noble metal that results from a cementation reaction.
