Abstract
A new composite complex salt—(NH4)1.8(Sn0.9Sb0.2)Cl6 was synthesized at room temperature from the starting materials SnCl4·5H2O and SbCl3. Its XRD pattern was indexed. The ATO nanoparticles were then obtained by sintering the composite complex salt at various temperatures. Analyses revealed the obtained ATO nanoparticles are single phase belonging to tetrahedral rutile structure.
