Description of the data | This dataset contains experimental data used to investigate slag derived from the remelting of solid oxide electrolyzer (SOEL) interconnects. It integrates bulk chemical composition determined by wavelength-dispersive X-ray fluorescence (XRF), crystalline phase identification and quantification by X-ray diffraction (XRD), and spatially resolved mineralogical analysis using scanning electron microscopy-based Mineral Liberation Analysis (SEM-MLA). In addition, a large-volume slag sample was scanned using X-ray computed tomography (XCT) to capture pore and inclusion distributions in 3D. The XCT scan volume covers approximately 6 × 5 × 2.5 cm at a voxel size of ~50 µm. All datasets are organized and include raw and processed data. README files are provided in each folder with detailed descriptions of sample preparation, analytical settings, and file content. This dataset supports reproducibility and further analysis in the context of slag design and resource recovery. | |

Abstract of the dataset | This dataset supports the manuscript titled “Chromium in Slag from SOEL Interconnects Remelting: Characterization and Recycling Potential”. 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. | |

Project abstract | The study investigates the formation, structure, and recovery potential of slags formed during the remelting of solid oxide electrolyzer (SOEL) interconnects. These interconnects, composed of high-alloy steels, generate oxide slags upon remelting that retain strategic elements such as chromium. It combines thermodynamic modeling with advanced mineralogical and microstructural characterization techniques to identify Cr-host phases, quantify their compositional selectivity, and evaluate their potential for selective recovery. Particular attention is given to Cr-rich spinels, which are assessed as candidates for Engineered Artificial Mineral (EnAM) strategies aimed at improving slag recyclability and compliance with environmental regulations. The research contributes to circular economy efforts in high-temperature metallurgical systems by linking slag design, element partitioning, and process optimization. | |
