Abstract

[001]C-Textured 0.55Pb(Ni1/3Nb2/3)O3–0.15PbZrO3–0.3PbTiO3 (PNN-PZT) ceramics are prepared by the templated grain-growth method using BaTiO3 (BT) platelet templates. Samples with different template contents are fabricated and compared in terms of texture fraction, microstructure, and piezoelectric, ferroelectric and dielectric properties. High piezoelectric performance (d33 = 1210 pC N−1, d33* = 1773 pm V−1 at 5 kV cm−1) and high figure of merit g33⋅d33 (21.92 × 10−12 m2 N−1) are achieved in the [001]C-textured PNN-PZT ceramic with 2 vol% BaTiO3 template, for which the texture fraction is 82%. In addition, domain structures of textured PNN-PZT ceramics are observed and analyzed, which provide clues to the origin of the giant piezoelectric and electromechanical coupling properties of PNN-PZT ceramics.
