Abstract
Here we report the 0.94(Bi0.5Na0.5)TiO3–0.06Ba(Zr0.055Ti0.945)O3 (0.94BNT–0.06BZT) lead-free ceramics was synthesized by two-step solid state reaction route. The structural, dielectric, ferroelectric, piezoelectric and electromechanical properties of the ceramics were studied, and showed excellent electric properties (Ps = 39.9 μC/cm2, Pr = 33.7 μC/cm2, Ec = 2.79 kV/mm, S = 0.20%, d33 = 174 pC/N, kp = 0.33). The depolarization temperature (Td) of the ceramics is about 65 °C, which is determined from the first hump of relative dielectric constant. The electromechanical factor kp disappears at 65 °C, is consistent with the depolarization temperature (Td) and the ferroelectric-antiferroelectric phase transition temperature (Tfe−afe) determined from the temperature-dependent P–E and bipolar S–E curves. These results indicate the 0.94BNT–0.06BZT ceramics has a good thermal stability in range of − 60–60 °C, and meets the actual demand.
