Lead-free piezoelectric ceramics (1−x)(Na<sub>0.5</sub>K<sub>0.5</sub>)NbO<sub>3</sub>-xBiFeO<sub>3</sub> (x=0∼0.07) were synthesized by the solid-state reaction. Differential scanning calorimetry (DSC) measurements revealed that an increase in the amount of BiFeO<sub>3</sub> dopant resulted in a decrease in the orthorhombic-tetragonal and tetragonal-cubic phase transition temperature of the material. One percent BiFeO<sub>3</sub> additive suppressed grain growth, which not only benefits the sintering of ceramics but also enhances the piezoelectric and ferroelectric properties, where d<sub>33</sub>=145pC/N, k<sub>p</sub>=0.31, Q<sub>m</sub>=80, P<sub>r</sub>=11.3 μC cm<sup>−2</sup> and E<sub>c</sub>=16.5 kV cm<sup>−1</sup>. As x<sub>BF</sub>>0.01, both piezoelectric and ferroelectric properties decreased rapidly with an increasing amount of dopant. |
