MICROWAVE FERRITE MATERIAL FOR MINIATURIZED CIRCULATOR, AND PREPARATION METHOD THEREFOR
Disclosed are a microwave ferrite material for a miniaturized circulator, and a preparation method therefor. The microwave ferrite material has a garnet structure as a main phase, and has a chemical formula as follows: Y3-aCaaZrbVcFe5-b-cO12. The preparation method comprises: mixing raw materials according to a stoichiometric ratio to obtain a raw material mixture; performing first wet ball milling on the raw material mixture to obtain a first slurry; sequentially drying and pre-sintering the first slurry to obtain first powder; performing second wet ball milling on the first powder to obtain a second slurry; sequentially drying and granulating the second slurry to obtain second powder; and sequentially forming and sintering the second powder to obtain a microwave ferrite material. Accordingly, the bandwidth of a miniaturized lumped circulator is widened so that the miniaturized lumped circulator meets 5G communication requirements; moreover, the device loss is reduced, and the communication quality is improved.
