Dielectric and microwave absorption properties of Ti3SiC2/cordierite composite ceramics oxidized at high temperature

Rational Design of a Core–Shelled Ti3AlC2@La2Zr2O7 Composite for High-Temperature Broadband Microwave Absorption

“…In the range of the X band, the EAB of the core–shelled TAC@LZO structure at room temperature is 4 GHz (2.57 mm), which exceeds those of most MAX phase related absorbers reported in the literature (Figure g and Table S3). − ,,− In comparison to the high-temperature MAMs with antioxidant resistance materials − (Figure h), whose EABs vary in the temperature range below 600 °C, the core–shelled TAC@LZO composite exhibits a stable EAB bandwidth at 25–600 °C. This result further indicates the advantages of TAC@LZO as an efficient and stable wide-temperature-range MAM.…”

Ceramic-based electromagnetic wave absorbing materials and concepts towards lightweight, flexibility and thermal resistance

“…Compared with magnetic metal-containing materials and polymers, ceramic-based systems exhibit high oxidation/ corrosion resistance, excellent mechanical properties, high melting points and superior thermal stabilities, which make them to be used under severe environments. Therefore, a great number of ceramic-based materials with excellent EMA performance have been widely investigated, such as SiC [21,[60][61][62][63][64][65][66][67][68], Si 3 N 4 [69][70][71][72][73], Al 2 O 3 [74][75][76][77], SiO 2 [78][79][80][81], SiOC [82][83][84][85], SiBCN [86][87][88][89], BaTiO 3 [90][91][92][93], Ti 3 SiC 2 [94][95][96][97], BCN [98][99][100], and others. The number of publications of ceramic-based EMW absorption materials increases with an increasing amount of EMW absorption-related publications (Figure 2), and the number of publications since 2018 has exceeded the total number of 2012-2017, implying the importan...…”

Review on Post-Treatment Emission Control Technique by Application of Diesel Oxidation Catalysis and Diesel Particulate Filtration

“…which will allow the microwaves to pass through it without heating the exhaust gases. The dielectric properties of a material determine its ability to get heated by microwaves [67]. The dielectric constraints consist of real and imaginary components as shown in equation number 5.…”
