Abstract

Lead-free piezoelectric 0.95(Bi_0.5Na_0.5Ti_1−xNb_x)O₃-0.05BaZrO₃ (BNTN-BZ5) ceramics (with x = 0–0.02) are synthesized by a conventional mixed oxide route. The crystalline phase, microstructure and electromechanical properties of the BNTN-BZ5 are investigated as a function of different Nb content. X-ray diffraction analysis shows the formation of single phase perovskite structure for all samples. The polarization response decrease while the dielectric and field-induced strain response increase when a small amount (x = 0.005) of Nb is incorporated in 0.95(Bi_0.5Na_0.5Ti)O₃-0.05BaZrO₃ (BNT-BZ5). An enhanced field-induced strain (S_max = 0.37%) with a corresponding dynamic piezoelectric coefficient (d*₃₃) of 542 pm V⁻¹ is observed for x = 0.005 at an applied electric field of 7 kV mm⁻¹.
