It develops a slightly yellowish or pinkish cast when oxidized by air. It is susceptible to weathering and dissolves slowly in most dilute acids. It does not react with a 1:1 mixture of nitric acid (HNO3) and 48.0% hydrofluoric acid (HF), … See more Scandium is a chemical element with the 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, together with yttrium and the lanthanides. … See more Scandium chemistry is almost completely dominated by the trivalent ion, Sc . The radii of M ions in the table below indicate that the chemical properties of scandium ions have more in common with yttrium ions than with aluminium ions. In part because of this … See more The addition of scandium to aluminium limits the grain growth in the heat zone of welded aluminium components. This has two beneficial effects: the precipitated Al3Sc forms smaller crystals than in other aluminium alloys, and the volume of precipitate-free … See more The world production of scandium is in the order of 15–20 tonnes per year, in the form of scandium oxide.

The biological effects of scandium refer to the bioactivity, behavior, and toxicity of Scandium element or compounds in cells, tissues, organs, and organisms. In general, scandium is present in low abundance in soil and water bodies, and it is not an essential element for organisms. The bioavailability of scandium is very low, so it ... Webmaking scandium oxide as a byproduct of alumina refining in the Ural Mountains were ongoing. The pilot plant was reported to have produced scandium oxide with purity greater than 99%. Based on pilot-plant test results, plans were in place for a 3-ton-per-year scandium oxide plant. In Dalur, Kurgan region, development of scandium recovery as a inconsistency\u0027s jg
