Ferroelectric Properties of Bi_0.5(Na_0.8K_0.2)_0.5TiO₃ Ceramics

Abstract:

Different processing conditions and the effect of secondary phases on ferroelectric properties of Bi_0.5(Na_0.8K_0.2)_0.5TiO₃ (BNKT) are studied. Ceramic powders are prepared by solid state reaction and different sintering temperatures (temperatures between 1075 and 1150°C) are analyzed. Finally, samples are characterized by X-ray diffraction, Raman microspectroscopy, Scanning Electron Microscopy, impedance spectroscopy, and density measurements. Through XRD patterns, the perovskite structure is stabilized; together with small peaks corresponding to a secondary phase associated with K_2-xNa_xTi₆O₁₃ phase. Moreover, the content of the secondary phase, d₃₃ piezoelectric constant and dielectric properties increase with sintering temperature.
