Abstract

In this study, the effect of poling conditions on the piezoelectric properties of 0.935(Bi0.5 Na0.5) TiO3 0.065BaTiO3 (BNT6.5BT) lead free ceramics was examined. The piezoelectric properties like piezoelectric constant (d33 ) and electromechanical factors (Kp ,Kt ) depend on poling field and poling temperature, while no remarkable effect of the poling time on the piezoelectric properties was detected in the range of 5-30 min.
