| Abstract Scope |
Operando synchrotron X-ray characterization enables investigation of the evolution of metals in molten salts under reaction conditions. In this talk we will present our latest studies using operando synchrotron X-ray nano-tomography by transmission X-ray microscopy, coupled with transmission electron microscopy. Temperature-dependent 3D morphological evolution pathways for Ni-20Cr in molten MgCl2-KCl were investigated to reveal the complex interplay between different processes concerning molten salt corrosion. The effects of different metal chloride additives will also be discussed. Furthermore, the reaction of pure Cr immersed in MgCl2-KCl will also be presented. By combining the imaging techniques with operando X-ray diffraction and spectroscopy, as well as atomic simulations, we probed how the morphological, chemical, and structural evolution of Cr proceed in molten salt. Overall, the work furthers our understanding of how metals interact with molten chloride salts, revealing underlying mechanisms in the demonstrated model systems. |
