Abstract
(1 − x)K0.5Na0.5NbO3-x(Bi0.5K0.5)ZrO3 [abbreviated as (1 − x)KNN-xBKZ, 0 ≤ x ≤ 0.08] lead-free ceramics have been fabricated by a solid-state processing route. Based on the x-ray diffraction data and temperature-dependent dielectric characteristics, an orthorhombic phase for x ≤ 0.03 and single rhombohedral one for x ≥ 0.05 at room temperature were determined. The cell volume firstly increases, then decreases and finally increases with increasing BKZ, depending on ionic size and crystallographic structure. For the sample of x = 0.05, a temperature-stable high permittivity (~ 1736 ± 15%) along with low dielectric loss tangent (≤ 5%) is recorded from 158°C to 407°C. In addition, the activation energies of dielectric relaxation and dc conductivity at high temperatures were characterized by impedance spectroscopy. A combined effect of lattice distortion and oxygen vacancies on the magnitude of activation energies was discussed.
