The world production of scandium is in the order of 15–20 tonnes per year, in the form of scandium oxide. The demand is slightly higher, [ 23 ] and both the production and demand keep increasing. In 2003, only three mines produced scandium: the uranium and iron mines in Zhovti Vody in Ukraine, the rare-earth mines in Bayan Obo , China, and ...
The group is also called the scandium group or scandium family after its lightest member. The chemistry of the group 3 elements is typical for early transition metals: they all essentially have only the group oxidation state of +3 as a major one, and like the preceding main-group metals are quite electropositive and have a less rich ...
[7] [5] Nilson's spectral analysis indicated a previously unreported pattern of lines. [8] Per Theodor Cleve demonstrated the equivalence of Nilson's scandium and Mendeleev's hypothetical ekaboron. [9] Nilson and Sven Otto Pettersson were the first to isolate titanium metal in a relatively pure form, extracting a 95% pure sample in 1887.

Thortveitite is a rare mineral consisting of scandium yttrium silicate (Sc,Y) 2 Si 2 O 7. It is the primary source of scandium. [2] Occurrence is in granitic pegmatites. It was named after Olaus Thortveit, a Norwegian engineer. It is grayish-green, black or gray in color. [3] [4] [5] [6]
Scandium acetate is a compound, with the chemical formula of Sc(CH 3 COO) 3. It exists in the anhydrous and the hydrate forms. It can be obtained by reacting scandium hydroxide or scandium oxide with acetic acid. [1] [2] It is a colorless, water-soluble solid. It decomposes into scandium oxide at high temperature.
