Ferroelectric Domain Structure and Array of Tetragonal and Rhombohedral Phase in PZT Ceramics at MPB Composition
Domain structure and the spatial arrangement of tetragonal and rhombohedral phases in PZT ceramics at MPB composition were investigated with a transmission electron microscope. Fringe Contrast and doublet spot splitting were observed in the image mode and the selected area diffraction pattern, respectively. Besides, triplet spot splitting was also observed in the other part of the specimen. These observations indicate that both the single phase regions and the regions which are comosed of alternatively arranged tetragonal and rhombohedral domains coexist in a PZT ceramics at the MPB composition.
