Co2Z type ferrite material and preparation method thereof
The invention discloses a Co2Z type ferrite material and a preparation method thereof. The chemical formula of the Co2Z type ferrite material is BaSr<3-x>Co<2>FeO<41>, wherein x is greater than or equal to 1 and less than or equal to 2, and y is greater than or equal to 21.6 and less than or equal to 24. The resonance frequency of the ferrite material is 2.0 GHz to 4.0 GHz. The preparation method of the Co2Z type ferrite material comprises the following steps: 1) mixing and ball-milling a Ba source, a Sr source, a Co source and a Fe source according to the proportion; 2) sintering the material obtained by ball milling in the step 1) at 1200-1300 DEG C for the first time; and 3) granulating the material obtained by the first sintering in the step 2), carrying out compression molding, and carrying out second sintering at 1000-1150 DEG C to obtain the Co2Z type ferrite material. The Co2Z type ferrite material provided by the invention has the characteristics of low sintering temperature, high resonant frequency and small powder particle size during preparation.
