    Research data for "Multiscale Characterisation of Lithium Aluminate in Laboratory- and Pilot-Scale EnAM Slags"
    (Technische Universität Bergakademie Freiberg, 2026-10-09) Rachmawati, Cindytami; Mongoljiibuu, Shine-Od; Weiss, Joao; Hamers, Maartje; Möckel, Robert; Friedrich, Bernd; Peuker, Urs A.
    This dataset supports the study “Applying Engineered Artificial Mineral (EnAM) Concept from Lab to Pilot Scale: Lithium Aluminate in Lithium-Bearing Slag Systems”. It contains experimental and processed data of a 125 kg pilot-scale slag (Slag P). The data comprise, X-ray diffraction phase analysis, micro-X-ray fluorescence (µXRF) elemental maps, X-ray computed tomography (XCT) volumes, and electron backscatter diffraction (EBSD) measurements. Derived data include segmented EnAM-rich clusters, cluster size and circularity, centroid-based nearest-neighbour distances, three-dimensional anisotropy, and individual lithium aluminate grain properties. The dataset enables investigation of scale-dependent changes in lithium-bearing phase formation, spatial distribution, clustering and intergrowth. µXRF and XCT data describe EnAM-rich clusters, whereas EBSD data resolve individual crystallographic grains. Documentation identifies sample positions, measurement conditions, processing procedures and the provenance of laboratory-scale comparison data.
