Description
Summary:Texture engineering is proved to be an effective strategy to enhance the piezoelectricity of piezoelectric ceramics in recent years. In this paper, a low-temperature sintered 0.24Pb(Ni[Formula: see text]Ta[Formula: see text]O[Formula: see text]PbZrO[Formula: see text](0.76[Formula: see text]PbTiO3 (PNT-PZT, [Formula: see text], 0.32 and 0.33) ceramic was studied. Texture engineering was introduced to improve the piezoelectric coefficient. Herein, [001] textured PNT-PZT ceramics were prepared at 1050∘C by templated grain growth (TGG) method using barium titanate (BaTiO[Formula: see text] platelet templates. The phase composition, microstructure, and electric properties of all ceramics were characterized in detail. The PNT-PZT ([Formula: see text]) textured ceramics shows the best comprehensive properties ([Formula: see text] [Formula: see text]pC/N, [Formula: see text] at 25∘C, [Formula: see text], [Formula: see text]C). This work provides a promising candidate material for ultrasonic transducers by texture engineering.
