Abstract

Oriented PbTiO3 ceramics were obtained by slip casting under a high magnetic field, and the orientation factor was 90%. Such highly oriented perovskite ceramics by slip casting under a high magnetic field have never been reported as far as we know. It was thought that dispersibility and crystallinity of the powder were important for orientation by slip casting under a high magnetic field. In this study, we controlled the dispersibility and crystallinity of powder by calcination temperature. As a result, the sample obtained from the powder calcined at 1100°C was oriented, but the one obtained from the powder calcined at 900°C was not. The powder calcined at 900°C is more aggregated than that at 1100°C and the crystallinity of the powder calcined at 1100°C is higher than that of the powder calcined at 900°C. It became clear that highly oriented PbTiO3 ceramics can be fabricated from the powder with high dispersibility and high crystallinity by slip casting under a high magnetic field.
