Abstract: A two-component microwave ferrite material, a preparation method therefor and an application thereof. The two-component microwave ferrite material comprises a first microwave ferrite material and a second microwave ferrite material. The preparation method comprises the following steps: (1) mixing a first microwave ferrite material and a second microwave ferrite material according to a formula amount, and then performing wet ball milling to obtain a ball abrasive; (2) drying the ball abrasive, sieving, and granulating; and (3) sequentially forming and sintering the granulated particles obtained in step (2) to obtain a two-component microwave ferrite material.

Abstract: Disclosed are a microwave ferrite material suitable for a 5G radio frequency device and a preparation method therefor. The preparation raw materials of the microwave ferrite material comprise a first microwave ferrite material and a second microwave ferrite material. In the microwave ferrite material provided by the present application, a double-component formula is introduced, proper ion substitution is employed, and ball milling and sintering processes are controlled, and therefore, the prepared microwave ferrite material has the characteristics of high saturation magnetic moment, high Curie temperature, narrow linewidth and low loss, and can be applied to industrial large-scale production of 5G radio frequency devices.
