Abstract:
1. A particulate material production method for producing a particulate material, comprising: vibrating a particulate material composition liquid in a liquid column resonance chamber having at least one nozzle to form a standing wave in the particulate material composition liquid caused by liquid column resonance so that droplets of the particulate material composition liquid are ejected in a droplet ejection direction from the at least one nozzle so as to fly in a space in a flight direction, wherein the particulate material composition liquid includes at least a solvent and a component of the particulate material dissolved or dispersed in the solvent, and the at least one nozzle is located at a location corresponding to an anitnode of the standing wave; feeding a gas in a direction substantially perpendicular to the droplet ejection direction to change the flight direction of the ejected droplets; and solidifying the droplets in the space to produce the particulate material.
