Scandium rarity
Web1.1 Rare Earth Elements. Rare earth elements (REEs) represent the group of 17 elements comprising 15 lanthanides, plus yttrium (Y) and scandium (Sc) (Table 1 ). Among the REEs, yttrium was discovered first in 1794 by a Finish chemist, Johan Gadolin who isolated an oxide and called it “yttria,” in a mineral collected from a quarry near the ... WebScandium. Relatively little XPS analysis of Sc and its oxides has been completed beyond the reporting of BE values taken of the metal and pure oxide (Sc2O3) [1,2]. This is presumably …
