摘要： SnO2超细粉用作透明导电膜和导电涂料具有广阔的应用前景．以ＳｎＣｌ４·５Ｈ２Ｏ和ＳｂＣｌ３为原料,在掺杂浓度Ｓｂ２Ｏ３∶SnO2＝９∶１００(重量比)的条件下,采用共沉淀法制得了纳米级的SnO2超细粉．运用差示扫描量热法－失重分析(ＤＳＣ－ＴＧ)、Ｘ射线衍射(ＸＲＤ)、透射电镜(ＴＥＭ)和紫外可见光光谱分析(ＵＶ)等观测手段对微粉末进行了表征,比较系统地研究了热处理工艺(温度、时间)对粉末颗粒度和电阻的影响规律,探讨了掺锑SnO2导电粉的显色特性．

Abstract: Tin dioxide ultrafine powders used as transparent conductive films and conductive paints have extensive
application prospects. Antimony-doped tin dioxide ultrafine powders in size of nanometers were prepared by chemical coprecipitation by using SnCl4·5H2O
and SbCl3 as precursors with the doped concentration of Sb2O3:SnO2 =9:100(weight rate). The characteristics of the powders were investigated by
differential scanning calorimetry and thermogravimetric analysis (DSC-TG), X-ray diffraction (XRD), transmission electron microscope (TEM) and ultraviolet
spectrum analysis (UV). The influences of heating temperature and heating time on the particle size and powders resistance were researched. The reason of the
powders emerging light blue was also derived.

Key words: conductive nanometer-sized antimony-doped SnO2 powders, heat-treatment, properties of antimony-doped SnO2 powders
