Abstract

Lead-free piezoelectric ceramics with compositions around the morphotropic phase boundary (MPB) x(Na_0.5Bi_0.5)TiO_3-y(K _0.5Bi_0.5)TiO₃-zBaTiO₃ [x + y + z = 1; y : z = 2:1] were synthesized using conventional, solid-state processing. Dielectric maximum temperatures of 280° C and 262° C were found for tetragonal 0.79(Na_0.5Bi_0.5)TiO₃-0.14(K _0.5Bi_0.5)TiO₃-0.07BaTiO₃ (BNBKT9) and MPB composition 0.88(Na_0.5Bi_0.5)TiO ₃-0.08(K_0.5Bi_0.5)TiO₃-0.04BaTiO ₃ (BNBK88), with depolarization temperatures of 224°C and 162°C, respectively. Piezoelectric coefficients d₃₃ were found to be 135 pC/N and 170 pC/N for BNBK79 and BNBK88, and the piezoelectric d ₃₁ was determined to be -37 pC/N and - 51 pC/N, demonstrating strong anisotropy. Coercive field values were found to be 37 kV/cm and 29 kV/cm for BNBK79 and BNBK88, respectively. The remanent polarization of BNBK88 (∼40 μC/cm²) was larger than that of BNBK79 (∼29 μC/cm ²). The piezoelectric, electromechanical, and high-Held strain behaviors also were studied as a function of temperature and discussed.
