Abstract
The domain walls and domain characteristics have been examined experimentally. In this study, a conventional lead zirconate titanate (PZT) piezoceramics were used. The specimen was designed to be a rectangular block shape. The specimens were loaded mechanically and electrically. The domain and domain-wall directions were altered with different direction. The domain direction was switched 90 degree by the mechanical loading, i.e., domain switching, where the (002) peak decreased and the (200) peak increased. In contrast, the domain wall direction was altered 90 degree when loaded electrically. With the applied stresses, domain direction and domain wall direction can be controlled. From the domain properties, it is considered that piezoelectric properties of PZT ceramics can be controlled by the applied stress.
