Kurzbeschreibung (Abstract)
This work successfully fabricated a novel CNWs/Ni 2 Si/SiOC nanocomposite ceramic material using a single‐source‐precursor derived ceramic approach. The material exhibits in‐situ formation of carbon nanowires (CNWs) and multiple core‐shell nanoparticles such as Ni 2 Si@C and SiC@C. The reaction mechanism of the precursor, the microstructure and phase composition, and the ceramics′ electromagnetic wave (EMW) absorbing properties were thoroughly investigated and discussed. The obtained CNWs/Ni 2 Si/SiOC nanocomposite ceramics possesses a minimum reflection loss (RLmin) of −43.5 dB, indicating excellent EMW absorbing performance. The in‐situ formation of CNWs and multi‐core‐shell nanoparticles (Ni 2 Si@C and SiC@C) in the ceramics play a crucial role in enhancing their EMW absorbing properties compared to pure SiOC ceramics.
