Abstract	In this study, (Na$_{0.465}$K$_{0.465}$Bi$_{0.07}$)(Nb$_{0.93}$Ti$_{0.07}$)O$_{3}$ ceramics with MnO$_{2}$ addition were prepared by conventional mixed oxide method. The effects of MnO$_{2}$ addition on the structural and electrical properties of the specimens were investigated for the application of piezoelectric devices. As the results of X-ray diffraction analysis, all specimens showed the typical polycrystalline perovskite structure without presence of the second phase. Sintered densities increased with increasing the addition amount of MnO$_{2}$ and the specimen added with 0.06 mol% of MnO$_{2}$ showed the maximum value of 4.87 g/cm$^{3}$. Average grain size increased and densification increased with an increasing of MnO$_{2}$ contents. The electromechanical coupling factor, dielectric constant, dielectric loss, d$_{33}$ and Curie temperature of the 0.06 mol% of MnO$_{2}$ doped (Na$_{0.465}$K$_{0.465}$Bi$_{0.07}$)(Nb$_{0.93}$Ti$_{0.07}$)O$_{3}$ specimens were 0.32, 1309, 0.016, 122 and 465 °C, respectively.
