  • Publication number: 20240420874
    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.

  • Publication number: 20240286959
    Abstract: The present application provides a high-saturation and low-loss bi-component microwave ferrite material, and a preparation method therefor and the use thereof. The high-saturation and low-loss bi-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 with a second microwave ferrite material according to the formula amounts, and then performing wet ball milling to obtain a ball-milled material; (2) drying the ball-milled material obtained in step (1), and sieving and then granulating same; and (3) sequentially forming and sintering the granulated particles obtained from step (2) to obtain a high-saturation and low-loss two-component microwave ferrite material.
