Characteristic
Scandium is a chemical element with the symbol Sc and atomic number 21. A silvery-white metallic d-block element, it has historically been classified as a rare-earth element
Phase at STP： solid
Melting point： 1814 K (1541 °C, 2806 °F)
Boiling point： 3109 K (2836 °C, 5136 °F)
Density (near r.t.)： 2.985 g/cm3
when liquid (at m.p.)： 2.80 g/cm3
Heat of fusion： 14.1 kJ/mol
Heat of vaporization： 332.7 kJ/mol
Molar heat capacity： 25.52 J/(mol·K)
Application
Applications for scandium were not developed until the 1970s, when the positive effects of scandium on aluminium alloys were discovered, and its use in such alloys remains its only major application.
