==Uses==
This [[metal]] is primarily useful when combined with others. Scandium and [[aluminum]] form an [[alloy]] which is used in the [[aerospace]] industry. The [[Russian]] [[military]] [[aircraft]] [[MiG-21]] and [[MiG-29]] also used this material. However, this [[alloy]] is very expensive, so [[alloy]]s of [[titanium]] are much more commonly used in [[aircraft]]. Scandium is also used in sporting equipment, revolvers, and bicycles. Also, scandium iodide with sodium iodide is used to create gas-discharge lamps. A radioactive isotope of scandium is also used as tracing agent to assist in crude oil analysis on oil rigs.<ref>http://wanttoknowit.com/uses-of-scandium/</ref>
