<P>PROBLEM TO BE SOLVED: To provide an inexpensive coating method having superior mass productivity and imparting superior corrosion resistance, and to provide a metallic fine particle. <P>SOLUTION: This method for producing the fine particle of a metal M1 reduced by an element M2 comprises mixing an oxide powder of a metal M1 with a powder containing such an element M2 that the standard free energy of the formation of its oxide satisfies the relationship of ΔG<SB>M1-O</SB>>ΔG<SB>M2-O</SB>, and heat-treating the mixed powder in a non-oxidizing atmosphere. Then, the surface of the fine particle of the metal M1 is covered with at least one substance among M2, an alloy containing M2, the oxide of M2, and a nitride of M2. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
