NiCuZn ferrite material and manufacturing method thereof
The invention discloses a NiCuZn ferrite material and a preparation method thereof. The ferrite material comprises a main component and an additive. The main component is composed of 47-49 mol% of Fe2O3, 15-22 mol% of NiO, 25-30 mol% of ZnO, 4-7 mol% of CuO and 0.1-0.5 mol% of Co2O3. The additive is composed of A and B, wherein A accounts for 0.1-0.5 wt% of the whole material, and B accounts for 0.1-0.5 wt% of the whole material. A is BBSZ glass; and B is one or two of Ta2O5, SiO2 and SnO2. The nickel-zinc ferrite soft magnetic material disclosed by the invention has the characteristics of high initial permeability and low loss; under the frequency of 13.56 MHz, mu' is greater than 150, and mu' is less than 2; and the nickel-zinc ferrite soft magnetic material is very suitable for producing NFC (near field communication) ferrite magnetic sheets by an LTCC (low temperature co-fired ceramic) running technique.
