摘要：

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 (Pb0.92Sr0.08) (Zr0.52Ti0.48) O-3-Bi4Ti3O12 system, the significantly enhanced fracture toughness of 2.8 MPa.m(1/2) was easily achieved, whereas a much lower value of about 1.0 MPa.m(1/2) was measured for the pure PZT ceramics.
