Relationship between Structure and Infrared Radiation of Fe-Mn-O Ceramics
Fe-Mn-O ceramics have been synthesized by conventional solid state reaction.The structure and infrared radiation properties of (l+x) Fe2O3.MnO2 compounds were studied by X-ray diffraction (XRD) and IR radiation tester.X-ray photoelectron spectroscopy (XPS) analysis shows the valence states.The phases of all samples change from complex oxides to spinel-like structure with the increasing of x.And Fe and Mn element of all samples also have two different valence states existence.According to the measurement results of sheet resistance and the radiation tester analysis,the sheet resistance and infrared radiance have shown a corresponding variation,and the infrared radiation properties in the 3-5μm waveband are influenced by the carrier transport and the distortion of the crystal structure,the sample with x=0.4 exhibits the average emissivity is 0.94 in the 3-5μm waveband at room temperature,and the result shows that Fe-Mn-O compounds can application in energy-saving of high temperature in industrial furnace.
