Indium ist ein chemisches Element mit dem Symbol In und der Ordnungszahl 49. Im Periodensystem der Elemente steht es in der 5. Periode und ist das vierte Element der 3. Hauptgruppe, der 13. IUPAC-Gruppe, oder Borgruppe. Indium ist ein seltenes, silberweißes und weiches Schwermetall. Seine Häufigkeit in der Erdkruste ist vergleichbar mit der von Silber. Indium ist für den menschlichen Körper nicht essentiell, genauso wenig sind toxische Effekte bekannt. Das Metall wird heute zum größten Teil zu Indiumzinnoxid verarbeitet, das als transparenter Leiter für Flachbildschirme und Touchscreens eingesetzt wird. Seit der Jahrtausendwende hat die damit verbundene gestiegene Nachfrage zu einem deutlichen Anstieg der Indiumpreise und zu Diskussionen über die Reichweite der Vorkommen geführt.
