With the wide use of electronic products, electromagnetic (EM) wave leakage and interfer-ence have been a common problem. High-performance EM absorbing material is then in urgent need. SiC ceramics and ceramic matrix composites possess many advantages, such as high-temperature stability, resistance to corrosion and oxidation, high strength, low density and designable dielectric property, which make them good candidates for EM absorbing thermostructural material. Chemical vapor infiltration and polymer derived ceramics have drawn more and more attention because they can realize the de-sign of microstructures of ceramics, leading them the main methods to fabricate high-performance EM absorbing SiC ceramics. This paper reviewed the design, synthesis and EM absorbing mechanism of EM absorbing SiC ceramics.
