Abstract
A method for synthesizing a copper-silver alloy includes an ink preparation step, a coating step, a crystal nucleus formation step and a crystal nucleus synthesis step. In the ink preparation step, a copper salt particle, an amine-based solvent, and a silver salt particle are mixed, thereby preparing a copper-silver ink. In the coating step, a member to be coated is coated with the copper-silver ink. In the crystal nucleus formation step, at least one of a crystal nucleus of copper having a crystal grain diameter of 0.2 μm or less and a crystal nucleus of silver having a crystal grain diameter of 0.2 μm or less is formed from the copper-silver ink. In the crystal nucleus synthesis step, the crystal nucleus of copper and the crystal nucleus of silver are synthesized.
