Preparation and Characterization of Grain-Oriented Barium Titanate Ceramics using Electrophoresis Deposition Method under a High Magnetic Field

摘要

Grain-oriented Barium titanate (BaTiO_3) ceramics were prepared using an electrophoresis deposition (EPD) method under high magnetic field of 12 T and sintering at 1350 °C. It was found that BT03 and BTKK nanoparticles were necessary to synthesize the grain-oriented BT ceramics. The grain orientation was correlated with particles size and c/a ratio of lattice constants. The reason why the grain-oriented BT ceramics using the BT03 and BTKK were prepared was having the large values of the particles size and the c/a ration of lattice constants.
