Abstract

The electromagnetic (EM) characteristics and microwave absorption properties of the Nickel/Ti₃SiC₂ hybrid powders are studied in 8.2-12.4 GHz.With the enhancement of Ti₃SiC₂ content, the dielectric loss of the hybrid powders increases while the magnetic loss decreases compared with the pure Ni powders. A favorable microwave absorption property can be obtained by changing the Ti₃SiC ₂ content to tailor the EM parameters. The composite with 30 wt% Ni and 30 wt% Ti₃SiC₂ powders presents the optimum microwave absorption property. For the composite of 2.2 mm thickness, a reflection loss (R_L) below -10 dB is obtained in the frequency range of 8.2-12 GHz with a minimum R_L of -41.2 dB at the matching frequency 9.7 GHz. This study contributes to exploring the absorber with broad absorption bandwidth, low density and thin thickness.
