Abstract

The invention provides a two-component microwave ferrite material as well as a preparation method and application thereof. The two-component microwave ferrite material comprises a first microwave ferrite material and a second microwave ferrite material. The two-component microwave ferrite material can be applied to microwave communication devices. The preparation method comprises the following steps: (1) mixing a first microwave ferrite material and a second microwave ferrite material according to a formula ratio, and then carrying out wet ball milling to obtain a ball milling material; (2) drying the ball-milled material obtained in the step (1), conducting sieving, and conducting granulating; and (3) sequentially molding and sintering the granulated particles obtained in the step (2) to obtain the two-component microwave ferrite material. Tests show that the ferromagnetic resonance line width [delta]H of the obtained material is less than or equal to 18Oe, the saturation magnetic moment 4[pi]Ms is less than or equal to 1260Gs, the dielectric loss tg[delta]e is less than or equal to 2*10<-4>, and the Curie temperature Tc is more than or equal to 260 DEG C. The stability and reliability of the material are greatly improved, and the material is more beneficial to industrial production.

Description

technical field [0001] The invention relates to the field of microwave communication magnetic materials, in particular to a two-component microwave ferrite material and its preparation method and application. Background technique [0002] Microwave ferrite devices occupy an important position in microwave technology and are widely used in aerospace, satellite communications, electronic countermeasures, mobile communications, and medical treatment. As the core of the device, microwave ferrite materials are widely used in microwave ferrite circulator isolators. In the microwave system, the technical processing of the isolation of microwave transmission is realized. [0003] With the rapid development of microwave technology, the system has more and more urgent requirements for the miniaturization of components, and the volume of ferrite components is much higher than other components, so the task of miniaturization and light weight is particularly important. [0004] There a...
