摘要：

In this study lead-free solid solution (K0.5Na0.5)NbO3 was prepared, structure, dielectric parameters of ceramics were investigated. The doping of sintering aids did not affect the crystallographic structure of the ceramics significantly; all ceramic samples had a single-phase perovskite structure. Added elements CdO, ZnO, MnO2, V2O5 effectively decreased the sintering temperature of KNN by 50 degrees-80 degrees C. All sintering aids influenced sinterability, microstructure and dielectric properties of ceramics. Dielectric constant for doped samples increased from 6000 up to 8000; P-r = 15 mu C/cm(2), E-c = 9 kV/cm, d(33) = 110 pC/N, k(p) = 0.38 and Q(m) = 190 for MnO2 doped samples.
