COATED METAL FINE PARTICLE AND METHOD FOR PRODUCING SAME

摘要

A method for producing fine; coated metal particles comprising the steps of mixing Ti-containing powder except for Ti oxide powder with oxide powder of a metal M, an M oxide having a standard free energy of formation meeting the relation of ”G M-O > ”G TiO2 ; and heat-treating the resultant mixed powder at a temperature of 650-900°C in a non-oxidizing atmosphere, thereby reducing the oxide of the metal M with Ti to provide the resultant fine particles of the metal M with TiO 2 -based titanium oxide coating.
