自悬浮定向流法制备Ti纳米颗粒及结构表征
Preparation and Structure of Ti Nanoparticles by Flow-Levitation Method
摘要
Abstract
Ti nanoparticles were prepared by flow-levitation method. The morphologies, granularities, structure and properties of Ti nanoparticles were investigated by transmission electron microscopy, X-ray diffraction and X-ray photoelectron spectroscopy. The results show that the particles prepared by flow-levitation method are spherical and the average sizes gradually decreases with the increase of Ar flow rate. Under the flow rates of 0. 6, 0. 8 and 1. 0 m3/h, Ti nanoparticles with the average sizes of 59, 50 and 41 nm are obtained. In the air, Ti nanoparticles mainly react with O2 and form stable TiO2. Meanwhile, Ti nanoparticles react with N2 and vapor in the air, and a small amount of nitride and hydroxyl group were found.关键词
