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.Attribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/4::43::405::405-014::43::406::406-014::43::405::405-04
