Research Progress of High Temperature Microwave Absorption Materials

Abstract

High temperature microwave absorption material is significantly important to improve the viability of advanced weapon and equipment. This paper summarizes the research progress of high temperature microwave absorption materials. The current research status of SiC based oxygen-free ceramic materials, laminated ternary ceramics (MAX phases), carbon materials and metal oxides, including the methods of manipulating the electronic structure, doping, designing multilayer structure and designing porous structure to improve their absorption properties, together with the related mechanism is discussed. Oxidation and unclear mechanisms for microwave absorption performance at high temperature are the main problems in the present research of high temperature microwave absorption materials. Finally, the trend of developing applied research and designing smart high temperature microwave absorption material is also prospected.
