Description:
For developing excellent microwave attenuation materials in a wide band, two series of SiC-C (graphite) composites with different C additions were fabricated by pressureless sintering, using α-SiC and β-SiC green powder, respectively. β-SBC composites were more suitable for microwave attenuation materials than α-SBC composites. β-SiC composites with 3 wt% C additions exhibited the best microwave absorption: The most significant microwave attenuation was −40.5 dB, and most other attenuations were above −30 dB in the whole X band. The composites were prepared with cost-effective and easily controllable manufacturing process and can be considered as structure–function materials for particular applications.
