| Research Abstract |
Synthesis of functional nano-structured powders has been developed through reactive thermal plasma processing. Nano-sized titanium oxide powders has been prepared by the oxidation of solid and liquid precursors. The plasma-synthesized TiO_2 nano-particles showed phase preferences different from those synthesized by conventional wet processes. Nano-sized particles of high crystallinity and non-equilibrium chemical composition were formed by one-step via reactive thermal plasma processing. Also, high dispersion behavior of plasma-synthesized nanopowders was recognized. The ultrasonically irradiated suspensions show aggregate sizes close to the primary particle sizes evaluated by an image analysis. Ultrasonic irradiation was shown to be a powerful way to disperse nanoparticles even in concentrated aqueous suspensions.
