Abstract
The phase transition behavior and its effect on thermal stability of the piezoelectric properties of the (1 - x)[0.65PbMg1/3Nb2/3O3-0.35PbTiO3]-xBiZn1/2Ti1/2O3ceramics with 0 ≤ x ≤ 0.06 were investigated. The phase transition from the monoclinic to tetragonal phase was determined by the dielectric constant and elastic constant measurements. The temperature independent piezoelectric response with -d31= 188 pC/N was obtained from 175 to 337 K for the composition with x = 0.02. The enhanced thermal stability of piezoelectric response was achieved by shifting the monoclinic-tetragonal phase transition to the lower temperature.
