Piezoelectric properties of PbHfO 3-PbTiO 3-Pb(Mg 1/3Nb 2/3)O 3 ternary ceramics

Journal Article


Abstract


  • (1 – x)Pb(Hf1–yTiy)O3–xPb(Mg1/3Nb2/3)O3 (x = 0.1 ~ 0.25, y =

    0.555) ternary piezoelectric ceramics were prepared using

    the two-step precursor method. Morphotropic phase boundary

    (MPB) compositions, located at x = 0.18 ~ 0.22, were confirmed

    using X-ray diffraction and by their dielectric, piezoelectric

    and ferroelectric properties. The optimum dielectric

    and piezoelectric properties were achieved for the MPB composition

    0.8Pb(Hf0.445Ti0.555)O3–0.2Pb(Mg1/3Nb2/3)O3, with

    dielectric permittivity εr, piezoelectric coefficient d33, planar

    electromechanical coupling kp and Curie temperature TC being

    on the order of 2800, 680 pC/N, 70% and 276 °C, respectively.

    Of particular significance is that the new ternary ceramics

    exhibit comparable piezoelectric and electromechanical

    properties to commercial PZT5H ceramics, but with much

    improved TC, showing a potential for applications at elevated

    temperature.
