Abstract

Titanium (iv) oxide (amorphous, brookite, anatase, and rutile) fine particles have been synthesized by pyrolysis of an aerosol. As-received materials are constituted by hollow balloons of around 1–2 μm formed by very small crystalline nuclei, whose crystal size can be modified by annealing. By heating at 900 °C for 48 h individual crystals of around 1 μm are obtained. Intermediate sizes can be controlled as a function of the thermal treatment.
