PROCESS FOR PRODUCING METAL MICROPARTICLE AND COMPOSITION CONTAINING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a process wherein the aspect ratio of metal nanorods can be easily controlled, and the metal nanorods having the objective aspect ratio can be efficiently produced. SOLUTION: In the process for producing metal microparticles by reducing metal ions in an aqueous solution containing a surfactant, the aspect ratio of the metal microparticles is controlled by producing the metal microparticles in an environment where acid or alkali is added, or the aspect ratio of the metal microparticles is controlled by performing reduction reaction at a regulated liquid temperature.
