Preparation and Characterization of Absorbent Thin Films by Spray Pyrolysis Technique Ultrasonic
Abstract
By the technique Pyrolytic Spray Ultrasonic, films were obtained Fe2O3: Mn. The concentrations of Fe and Mn were modified, which allowed to obtain values of emittance and absorbance that are comparable with the commercial TiNOX absorber. Analyzes ray diffraction - x, show that the phase of the material remains unchanged even when the temperature increases. Finally, the roughness analysis is modified by increasing the temperature. Based on the results obtained, this material deposited by this technique can be considered an option as a new absorbent solar coating.
