Abstract

(Na0.52K0.44Li0.04)Nb_0.9-xSb_xTa_0.1O ₃ lead-free piezoelectric ceramics are prepared by a solid-state reaction method. With increasing Sb content, the transition temperature from orthorhombic to tetragonal polymorphic phase decreased. A composition (Na _0.52K_0.44Li_0.04)Nb_0.863Sb _0.037Ta_0.1O₃ is found to possess excellent piezo-electric and electromechanical performances (d₃₃ = 306 pC/N, k_p = 48%, and k_t = 50%), and high Curie temperature (T_C = 320°C). These results indicate that (Na _0.52K_0.44Li_0.04)Nb_0.863Sb _0.037Ta_0.1O₃ is a promising lead-free piezoceramics replacement for lead zirconate titanate.
