Preparing of Barium Titanate Using Chemical Method and Studying of Its Structural Properties

Abstract

Single crystalline BaTiO3 (BT) was prepared using TiCl4, BaCl2 and oxalicacid. The structure of the prepared nanocrystalline BT powders were a tetragonalperovskite according to XRD and HRTEM analysis. Annealing powder to 750oCshow that pure BT phase was formed according to XRD, TG, and FTIRspectroscopy. The TEM images of the prepared powder reveal sphericalmorphology of BT, while a finger twin, dendritic and embryo shape are observedof BT powder calcined at 230, 530, and 750oC respectively. SAED and HRTEMimages showed a high crystalline BT powder and a single crystalline BTrespectively.
