In this work, a large size lead-free piezoelectric single crystal, (K,Na,Li)(Nb,Ta,Sb)O-3 (KNLNTS) with the dimensions of 8.5 x 8.5 x 13.5 mm(3) 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 degrees C. The piezoelectric coefficients and electromechanical coupling factors of the [001](C) oriented KNLNTS single crystal are d(33) = 172.55 pC/N, d(31) = -71.90 pC/N, k(31) = 0.327, k(33) = 0.523, and k(i) = 0.541. In addition, the crystal shows good thermal stability so that it can be used for making high temperature electromechanical devices. (C) 2014 Elsevier B.V. All rights reserved.
