摘　　要：以硝酸铟为原料,尿素为沉淀剂,将反应物溶于乙二醇,放入聚四氟乙烯内衬的反应釜中于200℃反应,采用溶剂热法一步制得In2O3纳米粉体。研究了反应时间和温度对粉体的结构、表面形貌和粒度的影响,并初步探讨了反应机理。结果表明:所制粉体为类球形,平均粒径约为25 nm。制备过程无需高温煅烧、操作简单,所得产物纯度高、粒度均匀、分散性好。Indium oxide nano-powders were prepared from indium intrate and carbamide with a convenient solvent thermal method at 200 ℃. Ethylene glycol was used as the solvent. Effects of reaction time and temperature on the structure, morphology and size of the samples were studied. The reaction mechanism was also briefly discussed. The results show that the In2O3 nano-powders are sphere in shape and the average size is about 25 nm. The present single-step solvent thermal method is very facile and high purity In2O3 with even size distribution and good dispersity is conveniently achieved without further high temperature calcination.
