Abstract

In this work, a lead-free piezoelectric system based on (1-x)(K _0.48Na_0.52)(Nb_0.95Sb_0.05)O ₃-xBi_0.5(Na_0.7K_0.2Li _0.1)_0.5ZrO₃ [(1-x)KNNS-xBNKLZ] is developed, and a rhombohedral-tetragonal phase boundary is constructed in this system. The relationship between the phase boundary and the piezoelectric properties of the (1-x)KNNS-xBNKLZ ceramics is illuminated. The coexistence of a tetragonal phase and a rhombohedral phase is identified in the composition range of 0.03 < x < 0.05. For such composition, the ceramics show giant d₃₃ of ∼380 pC/N, high T_c of ∼290°C, and a good thermal-depolarization behavior (d₃₃ > 300 pC/N) of ∼210°C. We believe that the (1-x)KNNS-xBNKLZ system is very promising for lead-free piezoelectric applications.
