- Abstract
In this work, Ti3SiC2 powders were composited with BaFe12O19 to improve electromagnetic and microwave absorption properties. The hybrid Ti3SiC2/BaFe12O19 powders were prepared in two different ways: mechanical mixing and auto-combustion. The electromagnetic and microwave absorption properties of the powders were investigated in the frequency range of 8.2-12.4 gigahertz (GHz). For the hybrid Ti3SiC2/BaFe12O19 powders, the complex permittivity was higher while the complex permeability was lower than individual BaFe12O19 powders. In addition, the hybrid powders prepared by auto-combustion had higher complex permittivity and permeability than the mechanical mixing powders. The most favorable absorption performance was obtained for the sample with a thickness of 2.4 mm. The reflection loss value below − 5 decibels (dB) was in the frequency range of 9.3-12.4 GHz, with a minimum reflection loss value of − 14.6 dB at 10.9 GHz.
