摘要：以SnCl_4·5H_2O和SbCl_3为原料,采用化学共沉淀法制得纳米级掺锑二氧化锡(ATO)的前驱物,在一定条件下热处理,成功制备了直径为10-30nm,长为50-500nm的金红石结构的ATO纳米棒。运用热重分析(TGA)、X射线衍射(XRD)、透射电镜(TEM)及比表面仪(BET法)对纳米棒进行了表征,初步探讨了其形成机理,较系统地研究了热处理温度及热处理时间对粉体形貌结构和导电性能的影响规律。
Antimony-doped tin oxide(ATO) nanorods with rutile structure were successfully prepared from an- nealing nanoscale precursor powders which were produced by chemical coprecipitation by using SnCl_4·5H_2O and SbCl_3 asaraw material. The structure and morphology of ATO nanorods were investigated by thermogravimetric analysis (TGA), transmission electron microscope (TEM), X-ray diffraction (XRD) and BET methods. The results show that the di- ameter and length of the as-prepared nanorods are 10～30nm and 50～500nm respectively. The mechanism of formation of ATO nanorods was simply discussed. The influences of heating temperature and heating time on the structure and powder resistance were also investigated.
