Abstract

Ordered mesoporous inter-filled SiC/SiO₂ monolithic composites were prepared via nanocasting and cold-pressing, using polycarbosilane as precursor and mesoporous silica SBA-15 as structural template. Their high-temperature dielectric properties and microwave attenuation performances were evaluated at the temperature rang of 25–500° C in X-band (8.2–12.4 GHz). The results indicated that the composites exhibited good high-temperature microwave absorbing properties, and attenuation mechanisms were also proposed. The calculated reflection loss (RL) suggested that the ordered inter-filled SiC/SiO₂ composite will be a good candidate as microwave absorbing materials in high-temperature environment.
