Abstract

CeO ₂ and Zn-modified CeO ₂ microstructures have been synthesized by a facile hydrothermal method and their microwave absorption properties have been investigated in detail. Complex permittivity and permeability of CeO ₂ and CeZn paraffin composites have been measured over the range of 2-18 GHz. Excellent microwave absorption properties have been obtained for CeO ₂ and CeZn microstructures compared with ZnO nanoparticles. Especially, maximum RL increases with increasing the concentration of CeZn microspheres in the composites and minimal RL value is -35 dB with 70 wt.% CeZn microspheres at 2.0 mm thickness. This phenomenon is attributed to both unique structure properties and geometric effect of CeO ₂ and CeZn microstructures.
