摘要： A microwave ferrite material for a third-order intermodulation circulator and a preparation method therefor, the chemical formula being Y3-aCaaSnaInbMncFe5-a-b-cO12, 0.1≤a≤0.3, 0.01≤b≤0.1, 0.001≤c≤0.1. The preparation method comprises the following steps: (1) weighing; (2) first ball milling; (3) drying and preheating; (4) second ball milling; (5) granulation; and (6) post-treatment. The microwave ferrite material reduces the intermodulation interference between combined signals, and further improves the performance of communication systems and the coverage and capacity of networks. At the same time, it is ensured that the stability and repeatability of the preparation process are maintained at a good level, being suitable for mass production applications.
