Abstract

In this letter we report the effect of CuO and MnO₂ additives on the sintering behavior of 0.95(Na_0.5K_0.5)NbO₃-0.05BaTiO₃ ceramics. It was found that the composition corresponding to 0.95(Na_0.5K_0.5)NbO₃-0.05BaTiO₃ + 2.0 mol% CuO + 0.5 mol% MnO₂, sintered at 950 °C for 10 h, exhibited excellent piezoelectric properties corresponding to: k_p = 0.41, d₃₃ = 248 pC/N, Q_m = 305, ε₃^T/ε₀ = 1258, and T_c = 280 °C. These results indicate the prominence of this composition in lead-free systems.
