Li-series spinel microwave ferrite material and preparation method thereof
The invention discloses a Li-series spinel microwave ferrite material and a preparation method thereof. The invention firstly discloses the Li series spinel microwave ferrite material, the chemical formula of the Li series spinel microwave ferrite material is Li (0.5-0.5 a-0. 5b) ZnaCubMn0.02 Fe (2.48-0.5 a-0. 5b) O4, a is more than 0.20 and less than 0.30, and b is more than or equal to 0.01 and less than 0.03. The invention also provides a method for preparing the ferrite material. The obtained material has the advantages of high saturation magnetization, low dielectric loss and low ferromagnetic resonance line width. Besides, after a cosolvent and a low-melting-point oxide glass phase sintering aid are introduced into the method, the sintering temperature in the process of preparing the ferrite material can be reduced, the ferrite material is applied to ferrite microwave devices such as circulators, isolators or phase shifters, and the devices have the advantages of low insertion loss, high isolation and the like, and have wide application prospects. Good application prospects are realized.
