Lead-free piezoelectric ceramics lithium sodium potassium niobate (LixNayK1-x-y)NbO3 (LNKN100x/100y) have been synthesized by a conventional solid state process. The effects of MnO2 addition on the properties of (LixNayK1-x-y)NbO3(x=0.06, y=0.5)(LNKN6/50) ceramics were investigated. It was found that a morphotropic phase boundary (MPB) between orthorhombic and tetragonal phases is in the composition range 0.05<x<0.07. The piezoelectric constant d33 and the planar electromechanical coefficient kp of LNKN6/50 ceramics reach 222pC/N and 39%, respectively. As the amount of MnO2- doped increases, dielectric constant, piezoelectric constant and Curie temperature Tc of LNKN:Mn ceramics decreased, while mechanical quality factor Qm of LNKN6/50:Mn increased prominently compared to pure LNKN6/50 ceramics. The addition of MnO2 can also decrease the sintering temperature effectively of LNKN6/50 ceramics.
