Abstract
A method for producing a metal powder provided on the surface thereof with a glassy thin film, wherein a glassy substance is produced in the vicinity of the surface of the metal powder by spray pyrolysis from a solution that contains a thermally decomposable metal compound and a glass precursor that produces a glassy substance that does not form a solid solution with the metal produced from the metal compound by thermal decomposition, so as to form the metal powder provided on the surface thereof with the glassy thin film. The glass precursor is prepared such that the melting temperature Tmof the metal and the liquid phase temperature Tmof the mixed oxide of the glassy substance satisfy the following formula (1):−100 [° C.]≤(Tm−Tm)≤500 [° C.]  (1).
