Composite hexagonal ferrite material with high remanence ratio and low loss and preparation method thereof
The invention discloses a high-remanence-ratio low-loss composite hexagonal ferrite material and a preparation method thereof, and belongs to the technical field of ferrite material preparation. The hexagonal ferrite material comprises a W-type hexagonal ferrite main formula, an M-type BaFe12O19 hexagonal ferrite and a doping agent, the W-type hexagonal ferrite main formula comprises BaCO3, ZnO, CoO and Fe2O3, and an additive comprises Bi2O3, H3BO3 and SiO2. W-type and M-type composite hexagonal ferrites with an exchange coupling effect are synthesized by adopting a ceramic method, so that the remanence ratio and the coercive force of the composite hexagonal ferrites are improved, and the quasi-plane characteristic of a microwave device is favorably realized; the W-type and M-type composite hexagonal ferrites with low ferromagnetic resonance line width characteristics are obtained by optimizing the additive ratio and the process, so that the insertion loss of a quasi-planarization device is reduced, and engineering application is realized.
