摘　　要：以SnCl_4和尿素为主要原料,采用化学共沉淀法制备Sn(OH)_4前驱体,前驱体经煅烧处理后得到纳米SnO_2粉体,探讨了前驱体的洗涤条件和表面分散剂及干燥方式对SnO_2粉体团聚现象的影响。Sn （OH） 4 precursor was prepared by chemical co-precipitation method with SnC14 and urea as main rawmaterial. Nanometer SnOz powder was obtained by precursor calcination treatment. The effects of the precursor washing conditions, surface dispersing agent and drying method on the agglomeration of SnO2 powder were dis- cussed.
