Title:
METHOD FOR PRODUCING SILVER-COPPER ALLOY PARTICLES
Document Type and Number:
WIPO Patent Application WO/2013/073068
Kind Code:
A1
Abstract:
Provided is a method for producing silver-copper alloy particles. The provided method for producing silver-copper alloy particles is a method for mixing silver ions, copper ions and a reducing agent in a fluid, and separating a silver-copper alloy therefrom. This method is characterized in that the amount of a eutectic in the silver-copper alloy particles is controlled by using at least two types of reducing agents as the reducing agent. The method is further characterized by: using at least two types of reducing agents as the reducing agent; mixing the silver ions, the copper ions, and the two or more types of reducing agents in a thin-film fluid formed between two or more processing surfaces arranged so as to face one another, capable of approaching toward and separating from one another, and capable of having at least one surface rotate relative to the other; and setting the pH of the fluid after mixing to 8-13.
