Abstract

(Na0.5K0.5)NbO3 (NKN) and BaTiO 3 (BT) ceramics form a homogeneous solid solution. The relative density of the (1 - x)NKN-xBT solid solutions significantly decreased when x ≤ 0.07. Although the relative density of the 0.95NKN-0.05BT ceramic was very low, it had a high d33 value of 134pC/N. MnO2 was added to improve the piezoelectric properties of the 0.95NKN-0.05BT ceramics by enhancing their sinterability. The addition of MnO2 increased the density of the specimens, as well as improving the piezoelectric properties. The 0.9 mol% MnO2 added 0.95NKN-0.05BT ceramics showed the good piezoelectric properties of kp = 0.31, d33 = 194pC/N and ε3 T/= 800.
