Abstract
Abstract Bi 0.5 (Na 0.5 K 0.5 ) 0.5 TiO 3 + y wt.% Nb ( y = 0–1) piezoelectric ceramics were synthesized by solid state reaction. The effect of varying Nb concentration on various properties of BNKT ceramic has been investigated in detail. The effect of Nb-doping on dielectric and ferroelectric property has been presented. An increase in its depolarization temperature and Curie temperature with Nb concentration was observed. The electrical properties of pure and Nb-doped BNKT ceramic over a wide range of frequencies (20 Hz to 2 MHz) and temperature (30–430 °C) were studied using impedance spectroscopic technique.
