摘 要：<正>Nd and Sb doped SnO2 conductive nanoparticles were prepared by the complexation-coprecipitation method with Sn, Sb2O3 and Nd2O3 as the raw materials. Thermal behavior, crystal phase, and structure of the prepared conductive nanoparticles were characterized by TG/DSC/DTG, FTIR, XRD and TEM techniques, respectively. The resistivity of the prepared conductive nanoparticles was 0.12Ω·cm. TG/DSC/DTG curves show that the precursors lose weight completely before 750℃. FTIR spectrum shows that the vibration peaks are wide peaks in 731 617 cm-1, and the Nd and Sb doped SnO2 conductive nanoparticles have intense absorption in 4000 2000 cm-1. Nd and Sb doped SnOi have a structure of tetragonal rutile, and complex doping is achieved well by complexation-coprecipitation method and is recognized as replacement doping or caulking doping. TME shows that the particles are weakly agglomerated, and the size of the particles calcined at 1000℃ranges about 10 nm to 30 nm.
