Studies of Scandium in Various Solutions. I. An Ion-Exchange Study of Scandium(III) Chloride and Nitrate Complexes [PDF]

open access: yesBulletin of the Chemical Society of Japan, 1966
Abstract The complex formation of scandium(III) with chloride and nitrate ions has been investigated at 25°C. Scandium-46 was employed in conjunction with a cation-exchange resin (Dowex 50W X-12, 100–200 mesh) in the H+-form and the ionic strength was maintained at 4.0 m with perchloric acid.

Sc2[Se2O5]3: The First Rare-Earth Metal Oxoselenate(IV) with Exclusively [Se2O5]2− Anions

open access: yesCrystals, 2018
The scandium oxodiselenate(IV) Sc2[Se2O5]3 was synthesized via solid-state reactions between scandium sesquioxide (Sc2O3) and selenium dioxide (SeO2) with thallium(I) chloride (TlCl) as fluxing agent in molar ratios of 1:4:2.

Modification of aluminium alloys with rare metals – the basis for advanced materials in construction and transport

open access: yesНанотехнологии в строительстве, 2016
The method of process powder injection into aluminum melt shows much promise. Scandium is injected by the high-temperature exchange reaction between the salt melt and aluminum. The best salt compositions were selected.

Scandium-Promoted Direct Conversion of Dinitrogen into Hydrazine Derivatives via N–C Bond Formation

open access: yes, 2019
Direct conversion of dinitrogen (N2) into organic compounds, not through ammonia (NH3), is of great significance both fundamentally and practically. Here we report a highly efficient scandium-mediated synthetic cycle affording hydrazine derivatives (RMeN–

Sorption of Scandium from Acidic Chloride Solutions on Strong-Acid Cation-Exchange Resins: Comparative Assessment and Isotherm Modeling

open access: yesMetals
Recovery of scandium from chloride-bearing process liquors formed during titanium–magnesium production remains constrained by trace-level metal content and chemically aggressive solution matrices. Within the present study, the retention behaviour of Sc3+
