Abstract
Composition dependent Rayleigh and structural analysis was carried out on lead-free piezoceramics (1-x)(BaTi0.88Sn0.12)-x(Ba0.7Ca0.3) TiO3 at room temperature. The system exhibits a tetragonal (P4 mm) structure for x > 0.21, rhombohedral (R3m) for x < 0.13, and orthorhombic (Amm2) for 0.13 < x < 0.21. Rayleigh analysis suggests that the irreversible contribution to the dielectric response is enhanced in the single phase orthorhombic compositions in the vicinity of the R3m-Amm2 and Amm2-P4mm phase boundaries, and not in compositions exhibiting phase coexistences (x = 0.12 and 0.22). We also found a correspondence between the irreversible Rayleigh parameter and the coercive field in this system.
