| 摘要 |
According to one exemplary embodiment, a wide temperature range dielectric absorber includes a dielectric absorber comprising a blend of lanthanum oxide, strontium oxide, and cobalt oxide, and is represented by (1-z)[La1-xSrxCoO3±y]+z[La2-xSrxCoO4±y]. The dielectric absorber includes a first crystalline structure existing independently from a second crystalline structure causing the dielectric absorption composition to have a wide temperature range of electromagnetic radiation absorption. In one embodiment, the first crystalline structure is a perovskite crystalline structure and the second crystalline structure is a potassium nickel fluoride crystalline structure.
