Abstract

Official abstract text for this publication.

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.

First claim

Opening claim text (preview).

The invention claimed is: 1. A copper-silver alloy consisting of: Cu; and Ag, wherein the copper-silver alloy has an average crystal grain diameter of 0.1 μm or less, and satisfies a requirement that a difference between a peak of ( 111 ) plane angle of the Cu and a peak of ( 111 ) plane angle of pure Cu is at least 0.812% of the peak of ( 111 ) plane angle of the pure Cu and a requirement that a difference between a peak of ( 111 ) plane angle of the Ag and a peak of ( 111 ) plane angle of pure Ag is at least 0.231% of the peak of ( 111 ) plane angle of the pure Ag. 2. A conduction part comprising the copper-silver alloy according to claim 1 .
