Abstract

We report the piezoelectric and ferroelectric properties of (Na _0.5Bi_0.5TiO₃)_x-(BaTiO ₃)_y-(Na_0.5K_0.5NbO₃) _1-x-y ceramics for Na_0.5K_0.5NbO₃ rich end of composition (x, y ≤ 0.04 mol. %). These compositions were found to exhibit significantly improved thermal stability of piezoresponse. Variation of dielectric constant as a function of temperature revealed that orthorhombic-tetragonal (T_o-t) and tetragonal-cubic (T_c) transition temperatures for these compositions were in the vicinity of 0 °C and 330 °C, respectively. Dynamic scaling and temperature dependent X-ray diffraction analysis were conducted. Results are discussed in terms of intrinsic and extrinsic contributions to the piezoelectric response explaining the temperature dependent behavior.
