| 英文摘要: |
| Textured ferroelectric ceramics are a class of materials developed in the past 40 years
to improve performance of ferroelectric ceramics by texturing technique, which has attracted much attention for their piezoelectric properties far exceed random oriented ceramics and cost lower than
single crystals. This review focuses on advances in textured ferroelectric ceramics with perovskite
structure, including characterization and evaluation methods of textured ceramics, preparation process
of perovskite ferroelectric ceramics, influencing factors of texture degree, and development of
piezoelectric performances of representative ferroelectrics such as lead-based relaxor ferroelectrics,
(Na, Bi)TiO3-based, (K, Na)NbO3-based, BaTiO3-based and BiScO3-PbTiO3 based ceramics. Finally,
some hot issues in textured perovskite ferroelectric ceramics research are summarized, and future
development is also prospected. |
