Influence MnO2 on the Properties of (LixNayK1-x-y)NbO3 Ceramics
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
