摘要： 采用非均相成核法,在晶种上以络合法均匀生长Sn,Sb混合金属氢氧化物,合成了纳米ATO导电粉体。以粉体电阻、粉体粒径为指标进行实验,得到了最佳络合剂。系统研究了合成条件如掺杂浓度,反应温度、pH值、配体/Sb比等对最终粉体导电性能的影响。以TG-DTA、XRD、TEM等手段研究了晶粒生长过程。结果表明粉体为四方金红石型结构,平均粒径为10nm左右,粉体的团聚很少。

Abstract: ATO nanoparticles were prepared from Sn(OH)4 nucleus grown uniformly with Sn(OH)4 and Sb(OH)3 by a complex method. The effects of reaction conditions such as doping concentrations, pH, temperature and complexing agent/Sb on the resistance were investigated by means of TG-DTA,XRD,TEM. The results show that ATO nanoparticles synthesized possess tetrahedral rutile structure with an average grain size near 10nm and excellent electrical properties. TEM photographs show that the particles are weakly agglomerated.

Key words: ATO, nanoparticle, complex
