Scandium Metal is available as disc, granules, ingot, pellets, pieces, powder , rod, sputtering target, wire, and in numerous other forms and custom shapes. See research below. Ultra high purity and high purity forms also include metal powder, submicron powder and nanoscale, quantum dots, targets for thin film deposition, pellets for evaporation and single crystal or polycrystalline forms. Elements can also be introduced into alloys or other systems as fluorides, oxides or chlorides or as solutions. Scandium metal is generally immediately available in most volumes. Additional technical, research and safety (MSDS) information is available.

Scandium is a Block D, Group 3, Period 4 element. The electronic configuration is [Ar] 3d1 4s2. In its elemental form scandium's CAS number is 7440-20-2. The scandium atom has a radius of 160.6.pm and it's Van der Waals radius is 200.pm. Scandium is a metal that has many of the characteristics of the rare earth elements, particularly yttrium. It is a light material with a higher melting point than aluminum giving uses in aerospace and most recently, in racing bicycles and golf clubs. Doping zirconium oxide with scandium oxide produces a low temperature electrolyte in solid oxide fuel cells.
