摘要
采用以乙醇为溶剂的溶剂热法制备ITO纳米粉体,考察了溶剂热反应条件对ITO粉体导电性能的影响。研究表明:当反应温度低于250℃时得到的粉体为InOOH或In4Sn3O12和InOOH的混合物,在250和270℃下反应可得立方结构的ITO纳米粉体;粉体的电阻率随溶剂热反应温度和反应时间的增加而增大;ITO粉体电阻率随着共沉淀pH值的增大逐渐减小;ITO粉体电阻率随SnO2含量的增加先减小后增大,当SnO2掺杂比例为8%左右时,电阻率最低。
Indium tin oxide （ITO） nan opowder was prepared in ethanol solvent by solvothermal process. The influence of solvothermal conditions on electric performance of ITO nano-powders was investigated. The prepared products were InOOH or mixture of InOOH and In3Sn4O12 when the solvothermal tempera- ture was below 250 ℃. ITO nanopowders with cubic structure could be prepared at 250 and 270 ℃. ITO powders＇ resistivity gradually reduced with the in- crease of coprecipitation pH value, the solvothermal temperature and time. Powders＇ resistivity firstly re- duced and then increased with the SnO2 content ris- ing. The resistivity was the lowest at SnO2 content of 8%.
