In situ growth of the Y₃Si₂C₂ interphase in SiC_f‐reinforced mullite ceramics for enhanced electromagnetic wave absorption

Journal of the American Ceramic Society, Год журнала: 2025, Номер unknown

Опубликована: Март 22, 2025

Abstract To meet the rigorous demands placed on electromagnetic (EM) wave absorbing (EWA) materials by harsh service conditions and to reduce EM power density, development of ceramic‐based EWA with high reliability stability has become a subject significant focus. In this study, yttrium silicide carbide interphase was in situ synthesized silicon fibers fabricate Y₃Si₂C₂–SiC f composite molten salt method. These were then incorporated into mullite ceramic matrix, /mullite composites prepared gel injection molding, aiming at enhancing properties. The exhibited reflection loss −28.97 dB 2.44 mm thickness an effective absorption bandwidth 3.066 GHz, outperforming pure SiC due addition . A modified Drude–Lorentz model developed capture multi‐peak permittivity behavior composites. results showed that dipole relaxation hopping migration localized electrons played key roles overall microwave energy attenuation, which closely matched experimental data. Furthermore, simulations electric field distribution radar cross‐section confirmed superior capability practical application potential This study offers valuable theoretical insights design ‐reinforced materials.
