COMPOSITE COPPER PARTICLES, AND METHOD FOR PRODUCING SAME

WIPO Patent Application WO/2014/007064

A1

Each of composite copper particles according to the present invention comprises a core particle composed of copper and a coating layer arranged on the surface of the core particle and composed of an alloy of copper and tin, wherein the volume cumulative particle diameter (D50) at a cumulative volume of 50 vol% is 0.1 to 10.0 μm. It is preferred that the alloy is CuSn. It is also preferred that tin is contained in an amount of 3.0 to 12.0 mass%. The composite copper particles can be produced preferably by mixing an aqueous slurry containing core particles each composed of copper and a compound that serves as a tin source with a reducing agent for tin and then forming a coating layer composed of an alloy of copper and tin on each of the surfaces of the core particles.
