Perovskite type ceramic material and preparation method and application thereof
The invention belongs to the technical field of high-entropy ceramic materials, and provides a perovskite type ceramic material as well as a preparation method and application thereof, and the ceramic material is Srx (CryMnyFeyCoyNiy) O3, x ranges from 0.5 to 1.5, and y ranges from 0.1 to 0.3. The perovskite type ceramic material provided by the invention is compounded with paraffin according to the mass ratio of 4: 1, when the thickness is 2.8 mm, the absorption frequency band width can reach 2GHz, the lowest reflection loss can reach-43.17 dB, and the perovskite type ceramic material has the characteristics of wide effective absorption frequency band and high absorption strength under the condition of low thickness. The invention also provides a preparation method of the perovskite type ceramic material. The preparation method comprises the following steps: mixing an inorganic salt solution with a precipitant solution, and calcining to obtain the perovskite type ceramic material. Water is used as a solvent, highly toxic chemical reagents are not needed, and the method is environmentally friendly and free of pollution; and the preparation process is simple, low in cost and suitable for large-scale industrial production.
