摘要
以In、Sn硫酸盐为原料，采用超声波与化学共沉淀相结合的方法制备纳米ITO粉末，用TEM，SEM，XRD，BET等现代分析测试手段对制备的粉末进行表征。在反应温度为60～75℃，In^3＋浓度〈160g／L，氨水浓度〈400g／L，终点pH为6．8～8的条件下，得到的纳米ITO粉末颗粒呈球状，团聚少、分散性好，In2O3：SnO2（质量）=9：1，平均粒径〈50nm，比表面积〉15m^2／g。
The nanometer powders of Indium Tin Oxide （ITO） are prepared with In2 （SO4）3 and Sn（SO4）2 as raw materials by an ultrasonic co-precipitation method. And the ITO nanometer powders are characterized by using TEM, SEM and XRD. Under the optimal condition of reacting temperature of 60-75℃, In3 ＋ concentration 160g/L, ammonia water dosage 〈 400g/L, and pH value of 6.8-8, the ITO powders with cublic structure, well distribution, finer dispersing in matrix, In2O3 ： SnO2 （mass） = 9 ： 1, the mean grain size is 〈 50nm and specific area 〉15m^2/g are obtained.
