Porous ceramic wave-absorbing material loaded with magnetic particles and preparation method of porous ceramic wave-absorbing material
The invention provides a porous ceramic wave-absorbing material loaded with magnetic particles and a preparation method of the porous ceramic wave-absorbing material. The preparation method comprises the following steps: mixing ferroferric oxide, a pore forming agent, raw material powder and the like, molding, and sintering to obtain the porous Fe3O4-loaded Si3N4-SiC composite ceramic wave-absorbing material. According to the technical scheme, the poor wave absorbing performance of the Si3N4-SiC multiphase ceramic in the X wave band (8.2-12.4 GHz) is improved, and the obtained Si3N4-SiC porous ceramic loaded with the magnetic particles is low in density and thin in thickness and can be used for various anti-electromagnetic interference fields.
本发明提供了一种负载磁性颗粒的多孔陶瓷吸波材料及其制备方法，包括通过四氧化三铁、造孔剂和原料粉等混合、成型、烧结后得到多孔负载Fe3O4的Si3N4‑SiC复相陶瓷吸波材料。本发明的技术方案改善了Si3N4‑SiC复相陶瓷在X波段(8.2‑12.4GHz)较差的吸波性能，所得负载磁性颗粒的Si3N4‑SiC多孔陶瓷密度低、厚度薄，可用于多种抗电磁干扰领域。
