Tarihi
Ferdinand Reich and Hieronymous Theodor Richter first identified indium in sphalerite by its bright indigo-blue spectroscopic emission line.
As no element was known with a bright blue emission they concluded that a new element was present in the minerals.
Richter went on to isolate the metal in 1864.

Uygulamalar
Indium's current primary application is to form transparent electrodes from indium tin oxide in liquid crystal displays and touchscreens.
It is widely used in thin-films to form lubricated layers.
It is also used for making particularly low melting point alloys, and is a component in some lead-free solders.
