The microstructures and phase constitution of Bi₄Ti₃O₁₂ toughened PZT ceramics were characterized together with the fracture toughness and piezoelectric properties. By the present approach, the fracture toughness of PZT ceramics was significantly enhanced (K_IC = 2.8 MPa m^1/2) without dramatic degradation of the piezoelectric performance. The discussion on phase equilibrium concluded that some more stable bismuth layer compounds such as PbBi₄Ti₄O₁₅ should be adopted as a secondary phase to toughen PZT piezoelectric ceramics, and then the subsequent negative effects on piezoelectric performance might be suppressed.
