PROBLEM TO BE SOLVED: To solve problems of a preparation method of dissimilar metal-containing particles comprising depositing metal ions by chemical reduction, such as (1) that reproducibility of nano particle preparation is poor because of concurrent occurrence of self-decomposition of a reducing agent, (2) that it is difficult to make a reductive reaction occur only in a neighborhood of a surface of dissimilar metal nanoparticles, (3) that nanoparticles generated tend to coagulate, and (4) that it is difficult to control a ratio of a dissimilar metal in the dissimilar metal nanoparticles depending on a purpose of use of the dissimilar nanoparticles.SOLUTION: The method for producing dissimilar metal-containing particles comprises steps of: (1) preparing a mixture of a first kind of metal particles, a second kind of metal particles, and a heat-responsive polymer; heating the mixture at a specified temperature or higher for a specified time or longer; and cooling the heated mixture.SELECTED DRAWING: Figure 5 |
