Abstract

Lead-free piezoelectric 0.97(Bi_0.5Na_0.5Ti_1−xNb_x)O₃-0.03BaZrO₃ (BNT-BZ3) ceramics (x = 0 ~ 0.03) were prepared by a conventional solid-state reaction method. X-ray diffraction patterns revealed the formation of single-phase perovskite structure with x ≤ 0.015. The depolarization temperature and the dielectric constant decreased with increasing Nb content. The remanent polarization (Pr) and the piezoelectric constant (d₃₃) increased from 28 μC/cm² and 98 pC/N for x = 0 to 31 μC/cm² and 128 pC/N for x = 0.005, respectively. In addition, the electric field induced strain was enhanced with a maximum value S_max = 0.17% with a normalized piezoelectric coefficient of d*₃₃ = 283 pm/V at an applied electric field of 6 kV/mm for x = 0.015.
