Abstract:
1. A method of synthesizing copper-alloy particles comprising the steps of: (a) forming a solution from an alcoholic agent and a branched dispersing agent; (b) optionally stirring the solution; (c) optionally heating the solution up to 170° C. or less; (d) adding a copper precursor and a nickel precursor to the solution to form a reaction mixture; (e) heating the reaction mixture to a temperature in the range of 170° C. to 190° C.; (f) cooling the reaction mixture to below 170° C.; (g) adding an additional amount of copper precursor and nickel precursor to the reaction mixture; (h) heating the reaction mixture to a temperature in the range of 170° C. to 190° C.; and (i) maintaining the reaction mixture at a temperature in the range of 170° C. to 190° C. for a time sufficient to reduce the copper precursor and the nickel precursor to copper-alloy particles.
