The Effect of Process Parameters on the Synthesis of Ti and TiO2 Nanoparticles Producted by Electromagnetic Levitational Gas Condensation

The nanoparticles of ti and ti02 have attracted extensive research interest because of their diverse applications in, for instance, catalysis, energy conversion, pigment and cosmetic manufacturing and biomedical engineering. through this project, a one-step bulk synthesis method of electromagnetic levitational gas condensation (elgc) was utilized for the synthesis of monodispersed and crystalline ti and ti02 nanoparticles. within the process, the ti vapours ascending from the high temperature levitated droplet were condensed by an argon gas stream under atmospheric pressure. the ti02 nanoparticles were produced by simultaneous injection of argon and oxygen into the reactor. the effects of flow rate of the condensing and oxidizing gases on the size and the size distribution of the nanoparticles were investigated. the particles were characterized by scanning electron microscopy (sem), x-ray diffraction (xrd) and image analysis. the process parameters for the synthesis of the crystalline ti and ti02 nanoparticles were determined.
