Scandium an overview ScienceDirect Topics

Scandium-45 is a relatively easily accessible nucleus owing to its 100% natural abundance and high magnetogyric ratio, but the comparatively large quadrupole moment Q has restricted its application. In the solid state, the large Q can provide valuable information on the quadrupolar interaction as exemplified for ScCl 3 6H 2 O and Sc(O 2 CCH 3) 3 in Despite scandium losses were lower than 4%, it was obtained a high-pure mix of REE (high and light) after two precipitation steps. About 98% of impurities were removed using CaCO 3 at pH 3.5 followed by Ca(CO 3) 2 at pH 5.0 (da Silva et al., 2018). In another work, the authors tested sodium sulfate and disodium hydrogen phosphate for Recovery of scandium from various sources: A critical review

Recovery of scandium from bauxite residue—red mud: a review

1 Introduction. Red mud is a slimy caustic residue generated from alumina refining of bauxite ores. During the alumina extraction process, about 35 %–40 % of the bauxite ores go into the residue as highly alkaline red mud slurry (pH 10.0–12.5) which contains 15 %–40 % of solid phase in volume [ 1, 2 ]. Depending on the quality of bauxiteReactivity of scandium phosphinophosphinidene complexes is also mapped out, and appears to be easily tuned by the supporting ligand. The newly formed sp 3 carbon atom in 4 displays a featuredSynthesis and versatile reactivity of scandium Nature

Materials Proceedings Free Full-Text The Future of Scandium

With growing demand for renewable and clean energy technologies, the need in rare earth metals is increasing. Scandium, which is often considered a rare earth element (REE), is a critical metal mainly used in solid oxide fuel cells (SOFCs) and high strength aluminum alloys used in aerospace and 3D printing applications. Furthermore, scandium supply is the focus will be on the mixtures based on sodium-scandium and on sodium-rare-earth because these are most commonly used in the lamp industry at the moment.
