Abstract

In this paper the preparation, structure and dielectric parameters of ceramics from different powders of pure potassium sodium niobate (KNN) and KNN doped with 1.0 wt% of Li₂O, CdO, Bi₂O₃, MnO₂, V₂O₅ and WO₃ have been studied. The dopping of sintering aids did not affect the crystallographic structure of the ceramics significantly; all ceramic samples had a single-phase perovskite structure. Added elements Li₂O, CdO, MnO₂, V₂O₅ effectively decreased the sintering temperature of KNN (50°-80°C). All sintering aids influenced sinterability, microstructure and dielectric properties of ceramics. Dielectric constant for doped samples increased from 6000 up to 8000.
