The (111) oriented plate-like BaTiO3 (BT) particles with a tetragonal perovskite structure and a stoichiometric composition were successfully synthesized by a two-step molten-salt synthesis method (MSS). The as-synthesized BT particles preserved the plate-like shape of precursor Ba6Ti17O40 (B6T17) particles with (001) major crystalline face, and, however, had a preferred pseudo-cubic (111) orientation. BT particle with a high aspect ratio (1020 mu m in diameter and <1.5 mu m in thickness) was achieved as the soaking temperature and time were optimized to be 1170 degrees C and 5 h, respectively. Oriented particulate layer X-ray diffraction analysis revealed that the crystallographic (001) plane of B6T17 has a topotactic relation with the (111) plane of BT particles.
