The industrial pure Fe-Si-B-P-C metallic glass powders (MGPs) were found to have excellent microwave absorption properties in this paper. The effects of chemical corrosion on the electromagnetic (EM) parameters and absorption properties were investigated in great detail. After chemical corrosion with hydrochloric acid solution, a highly porous structure appeared on the surface of powders, which increased the interfacial polarization and permittivity of the MGPs. The MGPs exhibited good impedance matching and strong microwave absorption properties. When the corrosion time was 10 min at pH 3.0, the minimum reflection loss (RL) value of composites reached -68.9 dB at 8.88 GHz, where the thickness of the composites was only 2.6 mm.

本文发现工业纯Fe-Si-BPC金属玻璃粉末（MGP）具有出色的微波吸收性能。详细研究了化学腐蚀对电磁（EM）参数和吸收性能的影响。在用盐酸溶液化学腐蚀后，粉末表面出现了高度多孔的结构，这增加了MGP的界面极化和介电常数。MGP表现出良好的阻抗匹配和强大的微波吸收性能。当在pH 3.0下腐蚀时间为10分钟时，复合材料的最小反射损耗（RL）值在8.88 GHz时达到-68.9 dB，复合材料的厚度仅为2.6 mm。
