Abstract

In this paper, La0.8K0.2MnO3 powder was synthesized by sol–gel method. The phase structure, morphology of the composite have been characterized by X-ray diffraction, field emission scanning electron microscope. Testing of the microwave absorption was carried out by using the network analyzer Agilent HP-8722ES at room temperature. The results show that the La0.8K0.2MnO3 powder has excellent absorbing property. The maximum reflection loss is −33.51 dB at about 12.22 GHz with a thickness of only 1.25 mm. Moreover, the bandwidth with the reflection loss above 10 dB reaches about 2.1 GHz.
