Abstract
In this letter we report the effect of CuO and MnO2 additives on the sintering behavior of 0.95(Na0.5K0.5)NbO3-0.05BaTiO3 ceramics. It was found that the composition corresponding to 0.95(Na0.5K0.5)NbO3-0.05BaTiO3 + 2.0 mol% CuO + 0.5 mol% MnO2, sintered at 950 °C for 10 h, exhibited excellent piezoelectric properties corresponding to: kp = 0.41, d33 = 248 pC/N, Qm = 305, ε3T/ε0 = 1258, and Tc = 280 °C. These results indicate the prominence of this composition in lead-free systems.
