The properties of scandium compounds are intermediate between those of aluminium and yttrium. A diagonal relationship exists between the behavior of magnesium and scandium, just as there is between beryllium and aluminium. In the chemical compounds of the elements in group 3, the predominant oxidation state is +3.
Scandium oxide demand reaches 38 tonnes the in business-as-usual scenario in 2030. •. Demand reaches 5,500 tonnes in the assumed additional 10% scenario in 2030. •. Automobile industry demands 5,300 tonnes in the additional 10% scenario in 2030. •. This leads to the question of mass adoption or mass production first.
Scandium is a chemical element; it has symbol Sc and atomic number 21. It is a silvery-white metallic d-block element. Historically, it has been classified as a rare-earth element,[7] together with yttrium and the lanthanides. It was discovered in 1879 by spectral analysis of the minerals euxenite and gadolinite from Scandinavia.[8]

Scandium, atomic number 21. It is the first of the transition metals, and its discovery is entwined with that of vertical neighbours yttrium and lanthanum. The Swedish island of Resarö, near Stockholm, became a hotbed of elemental discovery in the late eighteenth, and early nineteenth, centuries.
The scandium content in the red mud was 80–120 g/t. Depending on the scandium separation technology, the yttrium content could reach 2.5–4.5 g/t. Moreover, as the starting materials, we used a mixture of alkali metal halide salts and man ganese oxide; to obtain a smallgrained structure of master alloy, we also added scandium and yttrium …
elemental scandium metal was not produced until 1960. Scandium in oxide form is referred to as scandia, or of course scandium oxide, and the chemical formula is Sc 2 O 3. Geology Scandium is widely dispersed in the lithosphere and forms solid solutions in over 100 minerals, most commonly as a trace constituent of ferromagnesian minerals.
The first main transition series begins with either scandium (symbol Sc, atomic number 21) or titanium (symbol Ti, atomic number 22) and ends with zinc (symbol Zn, atomic number 30).
