摘要：
Lead free ceramics (K-0.5 Na0.5+x)NbO3 (0 <= x <= 0.3, KNN-x) were prepared by a novel method mixing perovskite structure of NaNbO3 and KNbO3 powders. Effects of Na excess and sintering temperatures on phase structure, microstructure and electrical properties of KNN ceramics were investigated. Result showed that the single phase perovskite structure was obtained in the KNN-0.1 ceramic sintered at 1070 degrees C, which also showed optimized ferroelectric property with P-r = 7.16 mC/cm(2) and E-c = 7.95 kV/cm. The KNN-x ceramic with x = 0.2 showed optimized piezoelectric property with d(33) = 116 pC/N because of the homogeneous dense microstructure.
