Toughening of PZT piezoelectric ceramics by in-situ complex structures

A new approach for toughening PZT piezoelectric ceramics has been developed, where some piezoelectric secondary phase tending to form plate-like or columnar structures was incorporated into PZT matrix to generate the in-situ complex structures and therefore to enhance the fracture toughness. In (Pb...

Zusammenfassung:A new approach for toughening PZT piezoelectric ceramics has been developed, where some piezoelectric secondary phase tending to form plate-like or columnar structures was incorporated into PZT matrix to generate the in-situ complex structures and therefore to enhance the fracture toughness. In (Pb 0.92Sr 0.08) (Zr 0.52Ti 0.48) O 3-Bi 4Ti 3O 12 system, the significantly enhanced fracture toughness of 2.8MPa.m 1/2 was easily achieved, whereas a much lower value of about 1.0MPa.m 1/2 was measured for the pure PZT ceramics.
