Outline of Final Research Achievements |
This study focused on development of an innovative high production synthesis method for pure functional nanoparticles using modulated induction thermal plasmas with intermittent feeding of feedstock. This method was originally developed by our group and modified for high-production of various nanoparticles. As target functional nanoparticles, Al-doped TiO2 nanopowder was tried to be synthesized. Using the developed method, Al-doped TiO2 nanopowder was successfully fabricated with a high production of 400 g/h at 20 kW. In addition, to study the evaporation process of injected feedstock, two-dimensional spectroscopic observation was carried out. Results showed the position and timing of the feedstock evaporation, which would be important to improve the production rate of nanopowder further.
