Synthesis of Antimony-Doped Tin Dioxide Nanocrystalline by Self-assembly Deflagration Technique
Antimony-doped tin dioxide (ATO) nanocrystallines were successfully synthesized via a novel strategy called self-assembly deflagration technique, by using antimony chlorine and tin chlorine as raw materials and self-assembly compounds as fuels. The molar ratio of components in compound fuels was carefully controlled to assure the forming of stable foams and the subsequent rapid deflagration. The environment temperature schedule was set up according to the DTA/TG curves of the compound fuels. XRD, SEM,FTIR and Microhm measure instrument were used to characterize the as-synthesized products. The results showed that the azury pure rutile ATO crystal with diameter in the range of 9-10 nm can be formed under the optimal synthetic conditions and the XRD peak positions agree well with the standard tetragonal phase rutile tin dioxide crystal without other phases. A low volume resistance ratio below 1.00Ω.cm was attained when the mass ratio of antimony chlorine to tin chlorine is 0.05. The whole deflagration process was environment-friendly without releasing amounts of smog and does not need a washing process.The self-assembly deflagration mechanism was discussed.
