英文摘要：
（K0.47Na0.47Li0.06）NbO3 （KNLN） lead-free ceramics were prepared by molten salt synthesis （MSS） method using k2CO3-Na2CO3 eutectic mixtures as the flux. The microstructure and piezoelectric properties when sin- tered at 980- 1 030 ℃ were investigated. The calcined powders were examined by X-ray diffraction. The microstruc- ture of the calcined powders and sintered bodies was observed using a scanning electron microscope （SEM）. The pie- zoelectric constant d33 was measured using a quasi-static piezoelectric d33 meter. The planar coupling coefficient Kp was calculated by resonance-antiresonance method. The experimental data for each sample＇s performance indicators were the average values of 8 specimens. The relative densities of sintered specimens are above 97%, and the dielectric loss is below 0.03. It was found that （K0.47Na0.47Li0.06） NbO3 prepared by MSS is compact and lead-free. The piezoelectric constant d33 is 216 pC.N 1 and the planar electromechanical coupling factor Kp is 0.352.
