摘要：

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 mum formed by very small crystalline nuclei, whose crystal size can be modified by annealing. By heating at 900-degrees-C for 48 h individual crystals of around 1 mum are obtained. Intermediate sizes can be controlled as a function of the thermal treatment.
