Description
Scandium Metal Powder Product Overview
Scandium (Sc) is a silvery-white, light metal with a density of about 3.0 g/cm³. As a powder, it is available in spherical or dendritic forms in purities of 99.9% to 99.99%. It is one of the most expensive industrial metals because it is produced only in small quantities.
Even small additions of scandium, often a few tenths of a percent, greatly increase the strength and weldability of aluminum alloys, which makes Al-Sc alloys valuable in aerospace, sports equipment and 3D-printed components. Electronics producers use scandium in aluminum scandium nitride (AlScN) piezoelectric films for RF filters, deposited from scandium-containing targets. Scandium oxide also stabilizes zirconia electrolytes in solid oxide fuel cells.
Fine metal powders can be flammable, so they are handled under inert gas. Related rare earth materials include Gadolinium Powder and Lanthanum Oxide.
