中文摘要：
以攀枝花钛精矿作为初始原料，采用湿化学法制备铁钛氧化物纳米粉体。利用X射线衍射（XRD）、场发射扫描电子显微镜（FESEM／EDS）、BET氮气吸附法、紫外-可见漫反射光谱（UV—VisDRS）对合成的粉体进行表征，测试结果表明：合成了相组成为85．72％质量分数Fe2TiO5和14．28％质量分数TiO2（金红石）复合纳米晶粉体，平均晶粒尺寸为38nm；近似球形的粉体颗粒及其聚集体，比表面积为16．80m^2／g；粉体在波长250—600nm范围内均有较强的光吸收，由Fe2TiO5电子跃迁形成的起始吸收边为593nm，相应的能带宽度为2．09eV。
英文摘要：
Using Panzhihua ilmenite concentrate as the raw materials, iron titanium oxide nanocrystalline powders were prepared by wet chemical method. The prepared nano-powders were characterized by X-ray powder diffraction, field emission scanning electronic microscope, BET N2 absorption techniques and UV-Vis diffuse reflectance spectra. The results show that the synthetic nano-powders have the phase composition of 85.72wt. % FeETiO5 and 14.28wt. % TiO2, the average grain size is 38 nm, the surface morphology of powders is approximately spherical particle and the specific surface area is 16.80 m^2/g, the strong light absorption occurs at the wavelength range of 250-600 nm, electron transition of Fe2TiO5 causes the absorption onset of 593 nm and the corresponding band gap is found to be 2.09 eV.
