Dielectric characterization of BaxSr1−xFe12O19 (x=0.05−0.35) ceramics

摘要: Abstract BaxSr1−xFe12O19 (x=0.05, 0.15, 0.25, 0.35) ferrites were prepared by both the sol–gel and conventional solid state reaction techniques. The structural characteristics dielectric properties of these investigated compared. ceramics obtained method show homogeneous morphology single crystalline phase while those route exhibit less morphology, being accompanied a secondary (BaFe2O4). size grains varies in range 200–300 nm for x=0.05–0.35 when powders are and, 600–700 nm reaction. For same value x, BaxSr1-xFe12O19 via display higher permittivity lower losses compared to route.
