Infrared emissivity and spectroscopy, advanced metallic materials, alternative energy materials, phase transitions, crystallography


The TPM Group is a young group focused on infrared emissivity of materials. The upgraded emissometer allows precise spectral, directional emissivity measurements for a wide variety of materials from room temperature up to 1000 ºC. Besides performing fundamental studies on thermophysical properties of materials, selective coatings used in concentrated solar power have been extensively investigated. This radiometric technique is also applied to the study of oxidation kinetics of advanced metallic materials. To reach an overall interpretation of the materials’ behaviour the Group gets profits from its expertise physical metallurgy and solid state physics and on other complementary characterization techniques such as XRD or electron microscopy as well as thermography. It has established collaborations with other spectroscopy laboratories as well as with synthesis groups, both at national and international level, and also participates usually in projects with industry.
