The study focuses on characterizing the bulk composition, mineralogy, its distribution, and elemental distributions in slag generated during the remelting of Solid Oxide Electrolyzer (SOEL) interconnects. The data include X-ray Fluoroscence (XRF) data, X-ray Diffraction (XRD) pattern data, X-ray Computed Tomography (XCT) dataset, and Scanning Electron Microscopy (SEM)-based Mineral Liberation Analysis dataset.Attribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/4::43::406::406-03
