Abstract

In this work, a large size lead-free piezoelectric single crystal, (K,Na,Li)(Nb,Ta,Sb)O₃ (KNLNTS) with the dimensions of 8.5×8.5×13.5 mm³ was successfully grown by the top-seeded solution growth method. This KNLNTS single crystal with high compositional homogeneity is in the tetragonal phase at room temperature. The Curie temperature T_C of the tetragonal-cubic phase transition temperature is 210 °C. The piezoelectric coefficients and electromechanical coupling factors of the [001]_C oriented KNLNTS single crystal are d₃₃=172.55 pC/N, d₃₁=-71.90 pC/N, k₃₁=0.327, k₃₃=0.523, and k_t=0.541. In addition, the crystal shows good thermal stability so that it can be used for making high temperature electromechanical devices.
