Carbon composite cerium-doped manganese-zinc ferrite wave-absorbing material and preparation method thereof
The invention discloses a preparation method of a carbon composite cerium-doped manganese-zinc ferrite wave-absorbing material. The preparation method comprises the following steps: 1) weighing a manganese salt, a zinc salt, a cerium salt and an iron salt, adding into deionized water to prepare a mixed solution, adding a NaOH aqueous solution into the mixed solution under a stirring condition, heating the mixed solution to react, and filtering, washing, drying and calcining the reaction product to obtain the cerium-doped manganese-zinc ferrite with the chemical formula of Mn0.5Zn0.5CexFe2-xO4;2) mixing the cerium-doped manganese-zinc ferrite with a carbon source, and calcining the mixture to obtain the carbon composite cerium-doped manganese-zinc ferrite wave-absorbing material. Accordingto the prepared carbon composite cerium-doped manganese-zinc ferrite wave-absorbing material, the dielectric loss performance of manganese-zinc ferrite is enhanced through reasonable element doping;meanwhile, the cerium-doped manganese-zinc ferrite is compounded with carbon, so that the electromagnetic impedance performance of the wave-absorbing material is greatly enhanced, and the wave-absorbing performance and effective bandwidth are greatly improved.
本发明公开了一种碳复合铈掺杂锰锌铁氧体吸波材料的制备方法，包括如下步骤：称取锰盐、锌盐、铈盐、铁盐，加入去离子水中配制成混合溶液，搅拌条件下向所述混合溶液中加入NaOH水溶液，加热反应，过滤，洗涤，干燥，煅烧，即得化学式为MnZnCeFeO的铈掺杂锰锌铁氧体；将铈掺杂锰锌铁氧体与碳源混合，煅烧，即得到所述碳复合铈掺杂锰锌铁氧体吸波材料。本发明制备得到的碳复合铈掺杂锰锌铁氧体吸波材料通过合理的元素掺杂增强了锰锌铁氧体的介电损耗性能，同时将铈掺杂锰锌铁氧体与碳复合，大幅增强了吸波材料的电磁阻抗性能，极大提升了吸波性能和有效频宽。
