| Research Abstract |
In this work, we developed a 20kW-class high-power pulse-modulated induction thermal plasma system for nanoparticle synthesis. Using this system, the effect of pulse modulation of the coil current sustaining induction thermal plasmas on synthesized nanoparticles. This work targeted TiO_2 nanoparticle synthesis. Results showed that the pulse modulation enables us to control the mean diameter of the synthesized nanoparticles, and that it also provides 80-90% anatase phase in mass fraction of synthesized TiO_2 nanoparticles, and finally that the control on the diameter of the synthesized nanoparticles might be based on the decrease in averaged temperature in the reaction chamber by the pulse modulation.
