Abstract:
A method for producing a metal powder wherein a compound of the metal is used as a raw material and the compound is reduced, characterized in that it comprises a forming process of mixing the metal compound with a binding agent, forming the resultant mixture into a predetermined shape, and then firing, to prepare a formed product of the raw material for the metal, and a reducing process of contacting the formed product with an active metal, to thereby reduce the metal compound and form the metal.
