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 piezoelectric and electromechanical performances (d33=306pC/N, kp=48%, and kt=50%), and high Curie temperature (TC=320°C). These results indicate that (Na0.52K0.44Li0.04)Nb0.863Sb0.037Ta0.1O3 is a promising lead-free piezoceramics replacement for lead zirconate titanate.
