Abstract

Ternary system, (1-x)Pb(Hf 1-yTi y)O 3-xPb(Mg 1/3Nb 2/3)O 3 (x = 0-0.5, y = 0.45-0.70) was prepared using two-step precursor method. The phase structure, dielectric, piezoelectric, and ferroelectric properties of the ceramics near morphotropic phase boundary (MPB) have been investigated systematically. On the basis of the results of X-ray powder diffraction and dielectric-temperature measurement, the MPB region and isothermal map of Curie temperature (T C) for the ternary system were obtained. The optimum piezoelectric and electromechanical properties were achieved in the MPB composition 0.8Pb(Hf 0.445Ti 0.555)O 3-0.2Pb(Mg 1/3Nb 2/3)O 3, with piezoelectric d 33 being on the order of 680 pC/N, while the maximum high-field piezoelectric d 33 * of 780 pm/V was observed for 0.82Pb(Hf 0.445Ti 0.555)O 3-0.18Pb(Mg 1/3Nb 2/3)O 3 with tetragonal composition, due to the high extrinsic contribution induced by domain wall motion. In addition, the fracture toughness K IC and flexural strength σ f were measured and found to be 1.2 MPa·m 1/2 and 71.4 MPa, respectively, comparable to PZT-based ceramics.
