Abstract
Hydrothermally synthesized BaTiO3 was colloidally consolidated by slip casting and by electrophoretic deposition in a high strength magnetic field of 17.4 T. Textured BaTiO3 was successfully prepared by both processing techniques, with the {001} plane aligning normal to the direction of the magnetic field. The initial alignment in the green powder compact was preserved and enhanced after sintering from 1400 °C to 1500 °C. The sintering temperature hardly influenced the degree of texture in slip cast samples but did influence the grain size of all BaTiO3 ceramics and the degree of texture in the electrophoretically deposited samples. The BaTiO3 ceramics processed in the strong magnetic field showed crystallographic texture but not morphological, so the microstructure did not show any anisotropy. The highest Lotgering factor (0.85) was measured for the ceramics made by electrophoretic deposition and sintered at 1500 °C.
