共沉淀法制备纳米ATO粉末
Preparation of ATO nanoparticles by co-precipitation method
以SnCl4o5H2O和 SbCl3作为原材料，采用共沉淀法制备了纳米ATO粉体。利用四探针测试仪、场发射扫描电镜(SEM)以及激光粒度分析仪，研究了Sb掺杂浓度、煅烧温度、煅烧时间对ATO粉末电阻率、表面形貌和粒径分布的影响。结果表明：ATO粉末的电阻率随Sb掺杂浓度，煅烧温度及煅烧时间的增加呈先下降后增加的趋势，并且在掺杂量为10%，煅烧温度为800 C，煅烧时间为1.0 h优化条件下制备的纳米ATO粉末具有最小的电阻率值，为0.1625 Ωocm，团聚现象较少，平均粒径为210 nm左右。
O particles were achieved by co-precipitation method with SbCl3 and SnCl4o5H2O. The effects of Sb doped content, calcination temperature and time on the resistivity, morphology and particle size distribution of ATO powder were investigated by the four point probe instrument, scanning electron microscope and laster particle analyzer. The results showed that resistivity of ATO degraded firstly and then upgraded as the Sb doped concentration, calcination temperature and time increasing. Results also indicated that ATO powder prepared under the optimized condition, namely ATO doped with 10 mol% Sb content was calcinated at 800 C for 1h, had the lowest resistivity of 0.1625 Ωocm, less agglomeration with narrow size distribution and average size about 210 nm.
