We report a comprehensive comparative study of ferroelectric and piezoelectric properties of BNT-BKT-BT ceramics through the MPB (morphotropic phase boundary) zone, from the rhombohedral to the tetragonal phases in the system (97.5-x)(Bi0.5Na0.5)TiO₃ + x(Bi0.5K0.5)TiO₃ + 2.5(BaTiO₃), where x = 0 to 24.5 mol %. The structural transitions were studied by XRD patterns and Raman spectra. The MPB wa...
