Basic information of Scandium
Scandium (Sc, atomic number 21) is a rare earth element with atomic weight 44.955908. Its melting point is 2,806°F (1,541°C). The appearance of its metal form is silvery-white while slightly yellowish or pinkish cast when oxidized in air. It can be dissolved slowly in most dilute acids. Similar to the early founded lanthan and yttrium, in the fullerene cluster, scandium shows as +3 metal cation and enables a new type of host/guest nanostructured material. Scandium is a soft transition metal and could be in various forms such as powder , solid metal (sputtering target, disc, rod, lump, plate), alloys (mainly Al-Sc alloy), chemical compounds. Scandium chemical compounds include scandium oxide, scandium chloride, scandium carbonate , scandium fluoride, scandium nitrate, etc. Application of Scandium As a component of alloy, scandium is used mainly in aluminum-scandium alloys . Addition of scandium improves the grain re...
