“…Recently some ceramic materials attracted increasing interest due to their good MA performance at both ambient and high temperatures . SiC with high wear resistance, good oxidation resistance, and chemical stability was considered as a promising MA material applicable in harsh environment . As reported, both the RL value and effective absorption bandwidth (EAB) of bulk SiC can be enhanced with increasing temperature from 100°C to 500°C indicating a favorable potential for MA application at high temperature .…”

The dielectric properties of high‐temperature stable single‐source precursor‐derived SiC/HfCxN1−x/C ceramic nanocomposites are determined by microwave absorption in the X‐band (8.2–12.4 GHz) at room temperature. The samples synthesized at 1700°C, denoted as SiC/5HfCxN1−x/C‐1700°C and SiC/15HfCxN1−x/C‐1700°C ceramics, comprising ≈ 1.3 and ≈ 4.2 vol% HfCxN1−x, respectively, show enhanced microwave absorption capability superior to hafnium‐free SiC/C‐1700°C. The minimum reflection loss of SiC/5HfCxN1−x/C‐1700°C and SiC/15HfCxN1−x/C‐1700°C are −47 and −32 dB, and the effective absorption bandwidth amount to 3.1 and 3.6 GHz, respectively. Segregated carbon, including graphitic carbon homogeneously dispersed in the SiC matrix and less ordered carbon deposited as a thin film on HfCxN1−x nanoparticles, accounts for the unique dielectric behavior of the SiC/HfCxN1−x/C ceramics. Due to their large reflection loss and their high chemical and temperature stability, SiC/5HfCxN1−x/C‐1700°C and SiC/15HfCxN1−x/C‐1700°C ceramics are promising candidate materials for electromagnetic interference applications in harsh environment.

“…Furthermore, special applications in high temperature and/or corrosive working environment drive the needs for the exploration of heat and chemical resistant EMI shielding materials. Recently, a number of researches have been focused on investigating high temperature EMI shielding materials ,. As known, SiC can function at high temperature and/or under harsh working environment due to its low thermal expansion, good thermal shock resistance, high strength and good chemical inertness …”

Porous SiC ceramics were synthesized for its potential electromagnetic interference (EMI) shielding application, with the utilization of a biomass material as the porous template and carbon precursor. A silicon infiltration process was conducted in the temperature range of 1400–1600 °C with the absence of any catalyst to produce the porous SiC ceramics. The porous SiC ceramics were characterized using scanning electron microscope, X‐ray diffraction and microwave vector network analyses. It was found that significantly higher EMI shielding effectiveness can be achieved using a higher silicon infiltration temperature. The porous SiC ceramics synthesized at 1600 °C possess the highest shielding value, reaching 60 dB at a high frequency range from 10 GHz to 18 GHz. It was proposed that the porous structure of the SiC can increase EM shielding performance by attenuating EM waves via multiple internal reflection and transmission of the incident and re‐reflected waves through the SiC walls of the porous network.

“…Carbon fiber reinforced ceramic matrix composites (CMCs) are prime candidates for such applications because of high strength, hardness, chemical inertness, low density, and high service temperatures . Recently ceramic composites have also being evaluated for their multifunctional properties such as electromagnetic shielding, self‐healing, and self‐lubrication characteristics . A suitable fiber/matrix system and a processing route have to be selected first for the development of a CMC system for a specific application.…”

[6][7][8][9] A suitable fiber/matrix system and a processing route have to be selected first for the development of a CMC system for a specific application. While the choice of matrix is primarily determined by the loading nature and corrosiveness of the application environment, the fiber is selected based on the ultimate tensile strength required for the final application.…”

Carbon fiber reinforced silicon carbide (SiC) minicomposites were prepared from three variants of commercially available carbon fibers, viz., T300‐3K, T300J‐3K, and T300‐6K. The SiC matrix infiltration was done via chemical vapor infiltration process using methyltrichlorosilane as the precursor. Minicomposites were characterized for the composition and morphology of the matrix material deposited. It was found that the matrix contains 2H‐SiC along with the major phase 3C‐SiC. Cyclic tensile tests were carried out on the composites to understand the damage mechanism and load bearing characteristics under cyclic loading conditions. The dependence of peak and residual strains on the fiber volume fraction was studied. Oxidation of the CMCs in air at 1500°C was studied and the result was explained based on a five part process.
