Microwave ferrite material for ferrite devices, and preparation method thereof
The invention discloses a microwave ferrite material capable of being used for ferrite devices, and a preparation method thereof, wherein the ferrite belongs to a lithium ferrite material, the chemical component of the ferrite is LixZnyMnzBiuNiv(Dy,Tb)wFe2.26+/-gammaO4+/-delta, x is equal to 0.35-0.37, y is equal to 0.27-0.29, z is equal to 0.045-0.055, u is equal to 0.004-0.006, v is equal to 0-0.03, w is equal to 0-0.03, gamma is 0-0.0113, and delta is 0-0.02. The invention provides a method for adjusting the saturation magnetization intensity through a process, wherein the saturation magnetization intensity of the prepared microwave ferrite material can be controlled within the range of 4300-5100 Gs. The microwave ferrite material prepared by the invention has the characteristics of high remanence ratio (Ms/Mr is more than or equal to 0.9), low coercive force (Hc is less than or equal to 2Oe), low loss (loss tangent tan delta is less than or equal to 1*10<-3>) and the like.
本发明公开了一种可用于铁氧体器件的微波铁氧体材料及制备方法。该铁氧体属于锂铁氧体材料，化学成分为LixZnyMnzBiuNiv(Dy,Tb)wFe2.26±γO4±δ，其中：x＝0.35‑0.37，y＝0.27‑0.29，z＝0.045‑0.055，u＝0.004‑0.006，v＝0‑0.03，w＝0‑0.03，γ＝0‑0.0113，δ＝0‑0.02。本发明提出了通过工艺调节饱和磁化强度的方法，可以将制的的微波铁氧体材料的饱和磁化强度控制在4300‑5100Gs范围内。本发明制备的微波铁氧体材料具有高剩磁比(Ms/Mr≥0.9)，低矫顽力(Hc≤2Oe)，低损耗(损耗角正切tanδ≤1×10‑3)等特点。
