The pure phase (Zr_0.8,Sn_0.2)TiO₄ nano crystals have been prepared by hydrothermal-molten salt method. The effects of the pH of solvent system, the calcinations temperature and the ratio of composite molten salt on the phase composition and crystalline morphology have been investigated. The results show that the high pure phase (Zr_0.8,Sn_0.2)TiO₄ nano crystals with regular morphology were prepared at 1000 ^oC in NaCl-KCl salt system. The synthesized temperature of single phase (Zr_0.8,Sn_0.2)TiO₄ is lower and the crystal growth is more complete compared with the hydrothermal-solid state method. The rod-like crystalline grain are evenly distributed with a diameter of about 50–60 nm and can be used as start materials for preparing ZST textured ceramics. The (Zr_0.8,Sn_0.2)TiO₄ nano crystal has a certain photocatalytic effect and good UV shielding performance.
