BiFeGaO3-BaTiO3 (BFG-BT) based ceramics with a large piezoelectric coefficient are potential high per-formance lead-free piezoelectric compounds.in this work,textured and random BFG-BT ceramics were realized by the solid state reaction method with and without BaTiO3 (BT) templates.Textured ceramics were obtained by a reactive templated grain growth (RTGG) method leading to a high-temperature elec-tromechanical strain ofS =0.27％ at 40 kV/cm and to an effective piezoelectric coefficient (d33 *) up to 685 pm/V at 180 ℃.The easy movement of oriented domains enhanced the electromechanical strain under an applied electric field in textured sample (Lotgering factor f=66.3％).Structural investigations reveal that the proportion and degree of distortion of BFG-BT rhombohedral phase (R3c) reached its maximum in textured ceramics,resulting in large ferrodistortive displacements under electric fields.In addition,the dense nanodomains with low domain wall energies,inferred from the high-resolution transmission electron microscope (HR-TEM) observations,contribute to the extra displacement of the textured sam-ple under an applied electric field.In textured ceramics,the remnant polarization was stable (about 17μC/cm2) from room temperature to 180 ℃,contributing to the stable ferroelectric property at high tem-peratures.Through the introduction of BT templates,high-density nanodomains were formed and the Burns temperature was enhanced in textured ceramics.The electromechanical strain,polarization and dielectric behavior were correlated to the textured or random forms of the BFG-BT based ceramics.
