Abstract FeSi powder was modified by wet milling with different milling time. The morphology, particle size, electromagnetic parameters and wave absorbing properties were characterized by scanning electron microscope (SEM), laser particle size analyzer and vector network analyzer, respectively. The results show that the average particle size of FeSi powder decrease and the level of flattening increase with the increase of milling time. The simulated reflectivity results show that when the milling time is 8 h, the bandwidth of the absorption value under -15 dB is 2.8 GHz, and the minimum absorption peak value at 10.5 GHz is -28.3 dB.
