INFLUENCE OF MONOXIDES ADDITION ON SINTERING OF SODIUM-POTASSIUM NIOBATES SOLID SOLUTION

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 Li 2 O, CdO, Bi 2 O 3 , MnO 2 , V 2 O 5 and WO 3 have been studied. The dopping of sintering aids did not affect the crystallogra...

Description
Summary: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 Li 2 O, CdO, Bi 2 O 3 , MnO 2 , V 2 O 5 and WO 3 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 Li 2 O, CdO, MnO 2 , V 2 O 5 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.
