Lightweight high-entropy perovskite wave-absorbing material and preparation method thereof
The invention relates to the technical field of wave-absorbing materials, and discloses a lightweight high-entropy perovskite wave-absorbing material and a preparation method thereof, and the lightweight high-entropy perovskite wave-absorbing material is a high-entropy perovskite oxide. The chemical formula of the high-entropy perovskite oxide is Srx (AyMnyCryByCy) O3, x is equal to 1 to 3, and y is equal to 0.2 to 0.6; a, B and C are selected from any three of Fe, Co, Ni, Ti, Zn, Cu, Zr, Ga, Sn, Yb, Eu, Mo, Rh and Ru. According to the invention, the light high-entropy perovskite oxide is synthesized at a low temperature by using a one-step firing process and adopting a pure oxide as a raw material through proper doping elements and firing temperature. The high-entropy synthesized half-shell hexagonal prism high-entropy perovskite oxide structure with the large length-diameter ratio is beneficial to multiple reflection of electromagnetic waves in the material, reflection is reduced, the wave absorbing performance is improved, and the application range of the high-entropy perovskite oxide is expanded.
