Sc

Scandium is a silvery-white metallic element. Although abundant in the Earth’s crust in low concentrations, large concentrations of scandium in magmatic, hydrothermal or supergene deposits are scarce, and scandium is typically produced as a by-product to other metals. Scandium is a critical mineral that is used in the production of alloys for the aerospace industry, in solid oxide fuel cells, specialized lighting applications, ceramics, lasers, electronics and in alloys with aluminum to produce sporting goods.
