Optimization of Ti with modified SiC ceramics for electromagnetic absorption properties

Magnetic Multilayer Composites Based on Carbon Nanotubes Modified SiC/BaFe12O19 for Wideband Microwave Absorption

“…The results revealed that SiC nanowires/EG could exhibit an optimal reflection loss (RL) value of −52.76 dB at 6.91 GHz with a thickness of 3.05 mm and a wide effective absorption bandwidth (EAB) of 3.74 GHz . Wei et al reported that SiCTi ceramics using Ti-modified polycarbosilane polymer-derived ceramics technology effectively increased electromagnetic wave absorption performance, SiCTi ceramics minimum RL −16 dB at 8.9 GHz, and EAB 4.2 GHz . In conclusion, despite the considerable progress achieved in enhancing the absorption strength of SiC, improving the EAB of SiC composites is still a formidable task .…”

Preparation, testing, and design of a radar‐absorption polymethacrylimide foam

“…Aluminum foam is the most widely used metal foam, 5 and silicon carbide (SiC) foam is commonly adopted as a ceramic foam. 6 The commonly used polymer foams are composed of expanded polystyrene, 7 polyurethane (PU), 8 polyvinyl chloride, 9 and polymethacrylimide (PMI). 10,11 PMI foams are closed-cell rigid foams with higher mechanical performance (at present) than other polymer foam types.…”

“…Based on their type of foam particles, foam materials can be divided into metal, 2 ceramic, 3 and polymer 4 foams. Aluminum foam is the most widely used metal foam, 5 and silicon carbide (SiC) foam is commonly adopted as a ceramic foam 6 . The commonly used polymer foams are composed of expanded polystyrene, 7 polyurethane (PU), 8 polyvinyl chloride, 9 and polymethacrylimide (PMI) 10,11 .…”
