| Abstract: | One of the intrinsic and unique microstructural features in ferroelectric ceramics is that their grains consist of domains. It is well known that various properties of these materials depend on the configuration of these domains. In this paper, domain structures in ferroelectric ceramics are reviewed. Domain switching induced by electric field or/and mechanical loading is introduced and illustrated. In addition, the influence of domain switching on the fracture toughness of ferroelectric ceramics and the research progress are described. |
