Low-loss LiZnTiMn gyromagnetic ferrite material and preparation method thereof
The invention provides a low-loss LiZnTiMn gyromagnetic ferrite material and a preparation method thereof, and belongs to the technical field of magnetic materials. The gyromagnetic ferrite material comprises a main material and a composite sintering aid, the weight percentage of the main material is 99.0%-99.5%, and the weight percentage of the composite sintering aid is 0.5%-1.0%; the main material is Li < 0.42 > Zn < 0.27 > Ti < 0.11 > Mn < 0.1 > Fe < 2.1 > O < 4 >, the composite sintering aid is composed of Bi2O3 and Nb2O5, and the mass ratio of Bi2O3 to Nb2O5 is 5: (1-5). The low-temperature sintering of LiZnTiMn is realized by optimizing the sintering process and adding the composite sintering aid, the LiZnTiMn ferrite material with low loss is obtained, the coercive force of the material is reduced, and the performance of the material is optimized.
