Description 740-743
To explore the piezoelectric potential of Ta doping on the MPB- like composition Na0.685K0.315NbO3, ceramic pellets of
Na0.685K0.315Nb1-yTayO3 (y ≤ 0.05) were arranged by solid-state reaction method. For piezoelectric measurements, sintered
pellets were electroded, in parallel capacitor configuration, with silver coating deposited by direct current (dc) magnetron
sputtering of a silver target. Polarization and piezoelectric parameters were measured using a ferroelectric (PE- loop tracer)
and piezo- meter (AixACCT Systems, GmbH). Composition (y) variation of remnant polarization, coercive field, converse
piezoelectric coefficient (d*33), and polarization current measurements were carried out in the prepared compositions. The
remnant polarization (Pr) is 18.439 μC/cm2 with a coercive field (Ec) of 8 kV/cm for NKNT single crystals. d*33 was
observed 300.76 pm/V for y = 0.04 at the applied field of 22kV/cm.
