| Description | Journal: Chinese Physics Letters $(Na0.52K0.44Li0.04)Nb_{0.9-x}Sb_{x}Ta_{0.1}O_{3}$ 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 $(Na_{0.52}K_{0.44}Li_{0.04})Nb_{0.863}Sb_{0.037}Ta_{0.1}O_{3}$ is found to possess excellent piezo-electric and electromechanical performances $(d_{33}$ = 306 pC/N, $k_{p}$ = 48%, and $k_{t}$ = 50%), and high Curie temperature $(T_{C}$ = 320°C). These results indicate that $(Na_{0.52}K_{0.44}Li_{0.04})Nb_{0.863}Sb_{0.037}Ta_{0.1}O_{3}$ is a promising lead-free piezoceramics replacement for lead zirconate titanate. |
