PIEZOELECTRIC COMPOSITE CERAMICS IN PZT-Bi_4Ti_3O_12 SYSTEM
PZT／BIT复合压电陶瓷

In order to obtain piezoelectric materials with excellent mechanical properties, the piezoelectric secondary phase Bi4Ti3O12 was introduced into PZT ceramics. Microstructure, fracturetoughness and electronic performance were determined. The fracture tongh
