| Outline of Final Research Achievements |
Exact control of nucleation and growth processes is important for producing high-quality metal oxide nanoparticles with desirable properties (particle size, distribution, structure, composition) in the continuous hydrothermal synthesis method. We developed high-temperature and high-pressure microdevices for reducing heterogeneous nucleation in the devices and altitude control of nucleation process. We carried out nanoparticles production from both homogeneous and heterogeneous mixtures of starting materials, clarified the formation mechanisms, and examined the two-stage system for supplying starting solutions to control growth process. On the basis of the results, the design method of desirable nanoparticles was studied.
