Single crystalline BaTiO3 (BT) was prepared using TiCl4, BaCl2 and oxalic acid. The structure of the prepared nanocrystalline BT powders were a tetragonal perovskite according to XRD and HRTEM analysis. Annealing powder to 750oC show that pure BT phase was formed according to XRD, TG, and FTIR spectroscopy. The TEM images of the prepared powder reveal spherical morphology of BT, while a finger twin, dendritic and embryo shape are observed of BT powder calcined at 230, 530, and 750oC respectively. SAED and HRTEM images showed a high crystalline BT powder and a single crystalline BT respectively.
