Title the safe technology for Preparation of TiO2 by explosion method and property characterization of TiO2
Abstract
Explosion method is a synthesis technique for preparing nanomaterials under high temperature and high pressure by detonating the mixed explosives composed of explosive and the precursors, such as inorganic salts, organic salts, metal powders and containing water oxides.It possesses the particular features of simple operation, high-controlling accuracy, high efficiency, low costs and more energy-saving. This paper summarized the research and application developments of TiO2 nanoparticles on the physicochemical properties, preparation and applications.Finally in view of the specialty and novelty of detonation synthesis method in synthesizing nanomaterials, the detail research on preparing TiO2 dispersed particles by detonation method was carried out from the following aspects.
1.Take metatitanic acid as titanium oxide’s precursor, mixed with emulsion explosive to be explosive composition for detonation synthesis of titanium dioxide powder, & characterization on the structure and properties of titanium dioxide.
2.The influence of detonation on microstructures of TiO2 dispersed particles prepared by detonation method were carried out systematically via X-ray diffraction measurements , and the basic law of the influence of detonation on the microstructures of TiO2 was demonstrated.
3.Study on heat treatment and impurity removal process for titania in morphology, particle size change, on the titanium oxide’s changes during heat treatment.
