摘要：

(Na0.52K0.44Li0.04)Nb0.9-xSbxTa0.1O3 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 (Na0.52K0.44Li0.04)Nb0.863Sb0.037Ta0.1O3 is found to possess excellent piezo-electric and electromechanical performances (d(33) - 306pC/N, k(p) - 48%, and k(t) = 50%), and high Curie temperature (T-c = 320 degrees C). These results indicate that (Na0.52K0.44Li0.04)Nb0.863Sb0.037Ta0.1O3 is a promising lead-free piezoceramics replacement for lead zirconate titanate.
