production of scandium and al

From this perspective, radionuclides of scandium, namely scandium-43 and scandium-44 (43/44 Sc) as positron emitters and scandium-47 (47 Sc), beta-radiation emitter, seem to fit ideally into the concept of theranostic pair (Mausner and Srivastava 1993; Huclier-Markai et al. 2018). Scandium-47 is also a low energy γ-emitter and allows …

The traditional method of introducing scandium into Al-Sc alloys is via a master alloy containing 98% aluminum and 2% scandium. NioCorp is now engaged in pilot-scale production of Al-Sc MA, containing up to 5% or more scandium by weight, and anticipates producing the pilot-scale ingots of Al-Sc MA over the coming weeks.

Metallothermic reduction. ・When Al was used as a collector metal for the reduction of Sc2O 3, metallic Sc was successfully obtained directly from Sc2O and alloyed. 3. in situ to form liquid Al-Sc alloy. ・When aluminum was used as a collector metal, excess calcium remained in the alloy sample in the form of Al4Ca.

Rare earths tailings, which contain Sc about 0.01–0.02% (Zhang et al., 2019), are the raw materials of scandium oxide production. They are crucial secondary resource including many valuable elements ( Amato et al., 2019 ) such as Fe, REs, Nb (niobium), Th (thorium), Sc, F (fluorine) and S (sulphur), which are produced from REs …

Fortunately, 43 Sc can be produced at a high level of radionuclidic purity and reasonable cost from a natural Ca target via the nat(40) Ca(α,x)-channel (40 Ca =96.94 atom% in natural abundance). In this reaction, two possible channels are considered: a direct route of 40 Ca(α,p) 43 Sc and an indirect route of 40 Ca(α,n) 43 Ti (EC , T …

The synthesis of 43 Sc can be accomplished through various production routes, with the 42 Ca(d,n) 43 Sc reaction being favorable due to its high yields at beam energies less than 10 MeV and the ...
