In this work , the influence of poling conditions (poling field, poling temperature and poling time) on the piezoelectric properties of 0.935(Bi0.5Na0.5) TiO3-0.065BaTiO3 (BNT6.5BT) lead-free ceramics was examined. Piezoelectric properties like piezoelectric constant (d33) and electromechanical factors (Kp ,Kt) depend on poling field and poling temperature, whereas different poling times, in the 5-30 min range, were not observed to have significant effect on the piezoelectric properties.
