Abstract
Polycrystalline Y-type hexagonal ferrite, with composition of Ba2−xBixZn0.8Co0.8+xCu0.4Fe12−xO22 (x = 0∼0.4), was prepared by the solid state reaction method. The effect of Bi substitution on phase formation, sintering process and magnetic properties were investigated in detail. The phase formation process was characterized by the means of powder X-ray diffraction (XRD). Bi3+ can substitute Ba2+ in Y-type hexagonal ferrite as divalent metal ion Co2+ substitute Fe3+ at the same time for electrovalence balance. As Bi amount is less than 0.3, the phase formation of Y-type hexagonal ferrite will not be destroyed. As Bi amount further increases, the lattice mismatch induced by the difference in ionic radii of Bi3+ and Ba2+ ions prevents the formation of pure Y-type phase. The samples with proper Bi substitution (0.05 0.1, the samples can be sintered well under 900 °C without any other addition. These materials are suitable for multilayer chip inductive components and devices.
