It is used in the electronics and ceramics industries. It is easily magnetized and very difficult to demagnetize. This suggests important future applications in solid-state and superconductor technologies. Found with other rare earths in monazite sand. The sand is often 50% rare earths by weight and 2.8% samarium. LpTkBg8HpvY Samarium

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. From the brilliant indigo line in its spectrum 62 1879 Paul Emile Lecoq de Boisbaudran France Named after "Samarskite" (a mineral)

Indium is considered to be of low toxicity

When it is bent, indium emits a high-pitched 'cry'

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.
