摘要：

TiO2 rutile of high purity was prepared through direct oxidation of the TiCl3 with atmospheric Oz at room temperature. The rutile phase obtained in this way is microcrystalline and has a high surface area. This phase suffered a crystal growth as a function of temperature (100 degrees C-700 degrees C) with textural properties modifications. (C) 1999 Elsevier Science Ltd. All rights reserved.
