摘要
对制备条件相同、晶粒度不同的锐钛矿TiO2 纳米晶体 (n A TiO2 )样品之晶粒微结构进行了细致的X射线衍射(XRD)研究 ,给出了标明晶面指数 (hkl)和晶面间距 (dhkl)值的系列XRD谱 ,并得到了晶面间距、晶格常数、轴比、晶胞体积等参数数值及其相对常规粗晶的变化情况 ,从而初步揭示出该样品晶粒微结构随粒度的变化情况。发现了锐钛矿TiO2
Samples of anatase type titanium dioxides nanocrystals (n A TiO 2),grown under similar conditions but with different grain sizes,were systematically studied with X ray diffraction.Various parameters of its microstructures,such as grain size,interplane spacing,lattice constant,axial ratios and cell volume were measured.Significant monotonous,anisotropic size effect on the microstructures of nanocrystalline anatase phase TiO 2 was observed.
