- Abstract
In order to obtain a high permeability and improve the microwave absorption properties in low frequency, this paper applied high-energy ball milling technology prepared flaky carbonyl iron powders (CIPs) with high permeability, and studied the Influence of milling time on the morphology, structure, impedance matching and low frequency microwave absorption properties. The result shows that the CIPs particles became flake shape and the deformation rate gradually increased with the increasing of milling time, in addition the permittibity and low frequency permeability increased significantly. The performance of electromagnetic attenuation was increased with the deformation rate ascent, but the impedance matching performance was decreased. The CIPs with the ball milling time of 8 h at 300 r/min has the best shape and excellent low frequency microwave absorption properties, with the minimum reflectivity reaching to -17 dB at 4.2 GHz. The minimum reflectivity of flake CIPs can reach to -26 dB at 7.2 GHz when the ball milling time is 6 h. The microwave absorption frequency can be adjusted by controlling the ball milling time, and study the relationship between them has great significance.
