<p>A method for manufacturing metal nanometer replaces two stages (firstly producing cuprous oxide, then producing copper particles by a reducing agent) of a metal particle producing process by one stage, such that it is capable of simplifying the working process obviously, obtaining metal copper particles easily by a short-time reaction at a low temperature (15-60 DEG C), omitting a complicated rinshing process of removing metal salts by secondary rinshing, and particle size dispersion is uniform and there is non requirement of a hierarchical process, thus the method is suitable for lot production. The method includes a first stage of dissolving metal precursor in a dissolvent containing a glycols dissolvent; a second stage of adding organic amine to the prepared solution, stirring until the color of the solution does not change; and a third stage of slowly adding more than one compounds selected from hydrazine derivatives, sodium hypophosphate, hydroxyl amine and sodium borohydride to the solution containing the organic amine of the second stage, so as to deoxidize and precipitate the metal(s).</p> |
