摘要
Nanocrystalline,single-phase undoped In 2O 3 was prepared by a polymer-network synthesis technique with indium nitrate as the starting material;several methods such as X-ray diffractometry (XRD) and transmission electron microscopy (TEM) were employed to obtain detailed information on the crystallography and microstructual appearance of In 2O 3 superfine powders. The influence of the concentration of starting solution,calcination temperature and time on the particle size was also that investigated by means of the XRD patterns. Results indicate that the obtained powders are mostly crystalline single phase with uniform size and also that the size of the products can be controlled under proper condition.
以硝酸铟为起始原料 ,利用高分子网络法合成纯的单相In2 O3纳米晶 .采用X射线粉末衍射 (XRD)和透射电镜 (TEM )等检测手段对所得粉体的组成、大小和微观形貌进行了表征和分析 .同时 ,根据XRD衍射图谱结果进一步讨论了不同原料质量浓度、煅烧温度和煅烧时间对产物粒径的影响 .实验结果表明所得晶粒晶相单一 ,粒度均匀并且可以选择适宜的条件制备所需粒径的纳米氧化物 .
