Abstract

FeCl∙6HO was used as raw material to produce FeO, using the solvothermal method with ethylene glycol as the solvent. FeO, with different particle sizes, was obtained via mechanical ball-milling by controlling the milling time. Effect of the milling time on the structure, morphology, and electromagnetic parameters of FeO were studied, and the absorption properties and mechanism of FeO, for different milling times were analyzed. The results showed that the integrity of the original small spherical structure decreased as the ball milling time increased. FeO showed excellent microwave absorptions as the milling time reached 2 h, the reflection loss reached the maximum of -21.19 dB at 4.64 GHz as the thickness was 6.55 mm.

摘要

以FeCl∙6HO为原料，采用乙二醇作溶剂的溶剂热法制备FeO。通过控制球磨时间，经机械球磨获得了不同粒径的FeO。研究了球磨时间对FeO结构、形貌和电磁参数的影响，并分析了不同球磨时间下FeO的吸波性能及机理。结果表明，随着球磨时间的增加，原始小球形结构的完整性降低。当球磨时间达到2 h时，FeO表现出优异的微波吸收性能，在厚度为6.55 mm时，4.64 GHz处的反射损耗达到最大值-21.19 dB。
