| description | Searching for microwaves absorption (MA) with outstanding resistance to harsh condition shows great potential in various special applications. As a typical high-temperature and conducting ceramic, TiB _2 can meet this requirement, but its high electrical conductivity will lead to high reflection of electromagnetic waves. In this paper, we find that TiB _2 ceramic can exhibit excellent MA performance after doping by C/N elements. The chemical structures, dielectric properties and MA performance of ZrB _2 ceramic are systematically measured and analyzed. The MA performance of TiB _2 ceramic reaches −21 dB at 8.00 GHz under a thickness of 2 mm. The results indicate that the MA performance of ZrB _2 can be ascribed to the multiple nonlinear dielectric resonance and polarization relaxation mechanism. This research significantly expands the application scope of TiB _2 ceramic to MA area. |
