“…32 A lattice spacing of 0.28 nm was observed in the composite, which was attributed to the (001) plane of WC. 33 The fast Fourier transform (FFT) pattern (inset of Fig. 2b) from the square area further confirms the hexagonal phase of CdS and WC@C. Element mapping from the high-angle annular dark-field scanning TEM image shows that the Cd, S, W, and C elements are homogeneously distributed over the nanorods (Fig.…”

“…The high-speed development of radar technology has seriously challenged the survival of aircraft. To reduce radar exposure signs, the working temperature of the tail nozzle and nose cone of an aircraft could reach 700 K. 1,2 For this purpose, various types of microwave absorbing materials have so far been designed. Nevertheless, the high-temperature performance is still not good enough.…”

Cr2AlC (CAC) has attracted increasing attention due to high conductivity and excellent oxidation resistance, which is useful for high-temperature microwave absorption. However, systematic research on microwave absorption performance of CAC at high temperatures is still lacking. In this work, CAC was synthesized by salt bath method followed by annealing at 500-950ºC. Effects of various annealing temperatures on compositions and electromagnetic properties were studied. Results revealed slight oxidation of CAC at annealing temperature of 500ºC, with formation of small amounts of Al2O3 and Cr2O3 on the surface. Increase in annealing temperature to 950ºC generated Al2O3 and Cr2O3 components in CAC. CAC annealed at 500ºC showed better microwave absorption properties than annealed at 950ºC and pure CAC. Effective absorption bandwidth (Reflection loss, RL< -10 dB) of CAC annealed at 500ºC was estimated to 2.3 GHz (9.7-12.0 GHz), and RLmin was -28.1 dB with thickness of 2.0 mm. The reason for this had to do with appropriate micro-oxidation, which could increase the permittivity of CAC and enhance dielectric loss capability for electromagnetic waves. In sum, these findings look promising to have referential significance for the application and promotion of CAC in the field of high temperature microwave absorption.
