Development of Continuous Production Method of Metal Oxide Nanoparticles Using a Micromixer and High-Temperature and High-Pressure Water

Abstract

  In this article, recent advances in development of continuous production method of high crystallinity metal oxide nanoparticles (NPs) through hydrothermal synthesis using micromixers and high-temperature and high-pressure water are summarized. This method has been attracting much attention as an innovative production technology of desired amount of NPs having desired particle properties for reducing development period of products using NPs and increasing application fields of NPs. Fundamental principle of this method, optimization of mixing condition, reaction rate and equilibrium of hydrothermal synthesis, and advantages of developed micromixers are described.
