Abstract：Tin and Sb2O3 were dissolved in HNO3， complexed with citric acid and obtained stable solution. Antimony-doped tin oxide （ATO） nano-particles were synthesized by hydrothermal and post-annealing method. The grain size， lattice parameters， specific surface area and the crystallinity of the ATO nano-particles changed with the Sb doping content and annealing temperature were researched. The results indicate that the hydrothermal method and free of chlorine ions to the synthesis process result in small particle size，narrow particle size distribution and low degree of agglomeration of the nano-particles. Higher annealing temperature accelerates the particle growth. The amount of substance ratio of Sb5+ andSb3+ in ATO crystal change with the Sb doping content and annealing temperature， which leads to the changes of SnO2 cell volume and conductivity of the nano - particles. The doped Sb element restricts the growth of the nano-particles and decreases the crystallinity of SnO2 phase.
