Abstract SiC?Fe composites are prepared by metal organic chemical vapor deposition (MOCVD) using silicon carbide (SiC) and iron pentacarbonyl (Fe(CO)5) as the precursors. The structure and morphology analyses demonstrate that the Fe nanoparticles have been deposited on the surface of the SiC particles. In terms of reflection loss (RL), the absorbing frequency band (AFB, the value of RL <?10 dB), and the matching thickness (tm), SiC-Fe composites show the best performances: minimum RL of -31.6 dB with tm=2.0 mm at 15.1 GHz, AFB of 12.9–17.3 GHz, indicating that Fe-doped SiC by MOCVD can significantly improve the electromagnetic properties of SiC and that SiC-Fe composites could be used as an effective microwave absorption material.
