Abstract
To provide a method for efficiently producing metal microparticles having a particle diameter of 1 μm to 10 μm, and a device for producing the same. A metal microparticle production method is used, which includes a particle generating step of generating primary particles by irradiating a metal lump in a solvent in a first tank with an ultrasonic wave, and a particle splitting step of irradiating the primary particles with an ultrasonic wave in a solvent in a second tank and splitting the primary particles to produce secondary particles. Further, a metal microparticle production device is used, which includes: a first tank that has a solvent and a metal lump; a first heating unit that heats the solvent in the first tank; a first ultrasonic vibrator that is disposed in the first tank and irradiates the metal lump with an ultrasonic wave to generate primary particles; a second tank that has the solvent and the primary particles; and a second ultrasonic vibrator that irradiates the primary particles with an ultrasonic wave to split the primary particles.
