Summary, etc. <p>To explore the piezoelectric potential of Ta doping on the MPB- like composition Na<sub>0.685</sub>K<sub>0.315</sub>NbO<sub>3</sub>, ceramic pellets of Na0<sub>.685</sub>K<sub>0.315</sub>Nb<sub>1-y</sub>Ta<sub>y</sub>O<sub>3</sub> (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<sup>*</sup><sub>33</sub>), and polarization current measurements were carried out in the prepared compositions. The remnant polarization (<em>P</em>r) is 18.439 μC/cm2 with a coercive field (<em>E</em>c) of 8 kV/cm for NKNT single crystals. d*<sub>33 </sub>was observed 300.76 pm/V for y = 0.04 at the applied field of 22kV/cm.</p>
