In recent years, a production of nanoparticles has been required in many fields such as production process for electronic materials, foods, and medicine. By using recrystallization process, nanoparticles can be formed by quenching a solution. We have generated monodisperse droplets by using an ultrasonic torsional transducer and a micropore plate to form fine nanoparticles by quenching droplets. In this nanoparticle production system, formed nanoparticles have a diameter of 79.9 nm when the applied voltage for the transducer and the diameter of micropore to generated micro droplets were 100 V_p‐p and 50 μm. We have successfully obtained fine nanoparticles from monodisperse droplets generated by using the ultrasonic torsional transducer. This result shows that the proposed system is effective for the miniaturization of the alum particles.

超声换能器使用单分散液滴产生纳米颗粒

近年来，在许多领域中要求生产纳米颗粒，例如电子材料，食品和药物的生产过程。通过使用重结晶过程，可以通过淬灭溶液来形成纳米颗粒。我们已经通过使用超声扭转传感器和微孔板生成单分散液滴，以通过淬灭液滴形成细小的纳米颗粒。在此纳米颗粒生产系统中，当传感器施加的电压和产生微滴的微孔直径为100 V _p-p时，形成的纳米颗粒直径为79.9 nm和50微米。我们已经成功地从使用超声扭转传感器产生的单分散液滴中获得了细小的纳米颗粒。该结果表明，所提出的系统对于明矾颗粒的小型化是有效的。
