Abstract
The present invention provides a novel process for synthesis of a copper-alloy particle with improved grain boundary properties. The process comprises the steps of: forming a solution from an alcoholic agent and a branched dispersing agent; forming a reaction mixture with the solution and a copper precursor and optionally a nickel precursor; heating the reaction mixture; cooling the reaction mixture; adding an additional amount of copper precursor and at least one precursor selected from the group consisting of: nickel, zinc, and bismuth; heating the reaction mixture; and maintaining the reaction mixture for a time sufficient to reduce the reaction mixture to copper-alloy particles.
Claims6
