摘要：Nanosized TiO2 powders were prepared for the first time by gaseous detonation method. The structure, composition and size distribution of the detonation product were systematically characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM). The results indicate the powders are a mixed crystal of rutile and anatase exhibiting non-spherical grains, and the average size of particles was between 20 and 40 nm. The results of detonation pressure measurement show that the reaction took place under a deflagration-to-detonation transition (DDT) course. (C) 2008 Elsevier B.V. All rights reserved.
