High-entropy ferrite wave-absorbing material and preparation method thereof

The invention provides a high-entropy ferrite wave-absorbing material and a preparation method thereof, and the preparation method comprises the following steps: S1, uniformly mixing MnO, Co3O4, FeO, NiO and Cr2O3 powder raw materials to obtain mixed powder; s2, after the mixed powder is pre-pressed into a blank, microwave sintering is carried out, the sintering temperature ranges from 900 DEG C to 1200 DEG C, the heat preservation time ranges from 0.5 h to 1 h, and the (MnCoFeNiCr) 3O4 high-entropy ferrite wave-absorbing material is obtained. According to the method, the wave-absorbing performance of the wave-absorbing material is improved, the synthesis cost of the material is effectively reduced, and the synthesis efficiency is improved. The wave-absorbing material prepared by the method is easy to process, and meanwhile, an ultra-wideband wave-absorbing effect can be obtained. 本发明提供一种高熵铁氧体吸波材料及其制备方法，包括以下步骤：S1、将MnO、Co3O4、FeO、NiO、Cr2O3粉体原料均匀混合，得到混合粉体；S2、将混合粉体预压制坯后，利用微波烧结，烧结温度900～1200℃，保温时间0.5～1h，即得(MnCoFeNi
