ABSTRACT
The grain orientation techniques of piezoelectric ceramics have attracted considerable attention because the grain oriented piezoelectric ceramics possess higher piezoelectric properties than polycrystalline ceramics and have the same Curie temperature as polycrystalline ceramics. In this paper, the research progress and trend of grain orientation techniques of piezoelectric ceramics are summarized with emphases on directional solidification technology, multilayer grain growth technique, templated grain growth and reactive templated grain growth technique. The future for the developments of grain orientation techniques of piezoelectric ceramics are also proposed.
