Abstract
The production of monodispersed fine TiO2 particles by Three-Phase Alkoxide Method was examined in a three-phase reactor of titanium tetraisopropoxide (TTIP) ethanol solution by the addition of water vapor, under various operating conditions. The rate of water vapor supplied to the reactor and the flow rate of the carrier gas ranged from 0.15 to 0.36g/min and from 3600 to 6000ml/min, respectively.
It was possible to obtain monodispersed fine TiO2 particles under almost all of the operating conditions examined. The rate of water supplied was found to affect the fractional conversion to fine TiO2 particles and the particle size of the products.
