Tabular SrTiO₃ crystals were synthesized by molten salt synthesis (MSS) method which included two steps: (1) synthesis of processing tabular precursor Sr₃Ti₂O₇ particles in molten KCl; (2) tabular SrTiO₃ crystal was obtained via the superposition of SrTiO₃ basic cell on the interface of Sr₃Ti₂O₇ particles based on the products of the first step. The conventional solid state reaction method was employed to synthesize SrTiO₃ particles in the reaction condition of 1200℃ for 4 h. The microstructures of these reaction products were analyzed by scanning electron microscopy (SEM) and X-ray diffraction pattern (XRD). The results showed that tabular SrTiO₃, obtained by MSS, had high purity and obvious tabular structure as well. XRD pattern showed that the conventional reaction products were obviously ball particles of SrTiO₃.

Key words: molten salt synthesis, tabular SrTiO₃, microstructure, solid state reaction
