Microwave ferrite material as well as preparation method and application thereof
The invention provides a microwave ferrite material and a preparation method and an application thereof. According to the microwave ferrite material and the preparation method thereof, by regulating and controlling the material composition and the preparation method of microwave ferrite, through combination of heating and cold isostatic pressing and combination of cold rolling and annealing treatment, when the size of the obtained microwave ferrite material is smaller than 7 mm, the requirements that the dielectric constant is controlled to be 14-31, the saturation magnetization intensity 4 pi Ms is 1200-2000 Gs, the Curie temperature is not lower than 200 DEG C, the dielectric loss angle tangent tan delta is smaller than or equal to 0.0002, and H is smaller than or equal to 50 Oe can be met, and therefore the requirements for miniaturization and low power consumption of a circulator in 5G communication can be met.
本发明提供了一种微波铁氧体材料及其制备方法与应用，本发明通过调控微波铁氧体的材料组成以及制备方法，通过升温与冷等静压的结合，以及冷轧与退火处理的结合，是所得微波铁氧体材料的尺寸为7mm以下时，能够满足介电常数控制在14‑31，饱和磁化强度4πMs为1200‑2000Gs，居里温度不低于200℃，介电损耗角正切tanδ≤0.0002且△H≤50Oe的要求，从而使其能够满足5G通讯对环形器的小型化与低功耗要求。
