Abstract
In this study, [Li0.04(Na0.54+xK0.46)0.96](Nb0.81Ta0.15 Sb0.04)O3 ceramics are prepared by the conventional solid-state solution processes. All the samples have high density, ranging from 4.72 to 4.77(g/cm3). The dielectric and piezoelectric properties were enhanced due to Na excess. As the result, excellent properties of density = 4.73(g/cm3), kp = 0.46, and d33 = 279(pC/N) were obtained in the composition with x = 0.005.
