Abstract

In the present work the preparation of titania nanosized spherical powders through a microemulsion precipitation method was investigated. The process is based on the precipitation of particles from a solution containing low-cost precursor, previously emulsified in an immiscible liquid. The precipitates were obtained dropping an acqueous solution of TiCl4into a stable microemulsion containing a light mineral oil and a surfactant. Different mixing techniques were evaluated. The synthesized titania nanopowders were characterized by XRD, BET, TGA and DTA, SEM and TEM. The as-synthesized powders were mainly amorphous and were subjected to thermal treatment. Nanosized homogeneous spherical powders with average particle size of 6 nm after synthesis and 30 nm after heat treatment were obtained.
