In order to improve the piezoelectric and aging properties of the lead-free Li 0.06 (K 0.48 Na 0.52 ) 0.94 (Nb 0.86 Ta 0.08 Sb 0.06 )O 3 piezoelectric ceramics, the conventional solid-state reaction method and the B-side pre-calcined method were achieved and compared in this paper. The physical and electrical properties of the lead-free Li 0.06 (K 0.48 Na 0.52 ) 0.94 (Nb 0.86 Ta 0.08 Sb 0.06 )O 3 piezoelectric ceramics material were investigated and discussed. For the B-side pre-calcined method, the ceramic material exhibited the excellent electrical and piezoelectric parameters. Finally, the electromechanical coupling factors, the resonance frequencies, and the resonance resistances of the lead-free ceramic materials were also discussed.
