摘要：
Spherical indium tin oxide (ITO) nanoparticles were synthesized by combustion method using citric acid as fuel and nitrates as oxidizer. The obtained ITO nanoparticles were characterized by TG-DSC, FT-IR, XRD, BET, TEM, and SEM. The ITO nanoparticles grew steadily with the increase of heat treatment temperature, and the 700 degrees C calcined particles had a crystallite size of 25.3 nm and a specific surface area of 26.1 m(2).g(-1). The avoidance of chlorine ions in the synthesis process decreases particle agglomeration and promotes powder densification. The 900 degrees C sintered pellet had a density of 67.6% of theoretical density (TD) and increased steadily to 97.3% for the 1400 degrees C sintered ceramics, respectively.
