Indium 99.99% (In) – 100 grams

Indium (In) is the softest of the non-alkali metals. Like gallium, indium is also silvery white, similar to tin. Indium is toxic if accidentally ingested and occurs only in compounds in nature.

• Czech Indium, Latin Indium, English Indium

An alloy of indium, gallium, bismuth, cadmium, lead, and tin is used to manufacture fusible fuses, used for example to trigger automatic fire extinguishing systems.

Galinstan, which is an alloy of gallium, indium, and tin, has a melting point of only -19 °C. It is used to replace toxic mercury in medical devices and thermometers. Galinstan is also used to produce single-crystal wafers – basic semiconductor discs that serve as a substrate for creating microcircuits.

When applied in a thin layer to a flat surface, indium forms a high-quality mirror surface, much more resistant to corrosion than classic silver mirrors. An indium mirror reflects the entire light spectrum, which is a great advantage. Indium mirrors are therefore among the highest quality mirrors.

Indium, like gallium, is part of light-emitting diodes (LEDs), laser diodes, components and semiconductors, display LCD screens, and touch screens. Indium also finds application in nuclear energy.

The high resistance of indium to corrosion and wear is the reason for electroplating aircraft engine bearings with this metal. In the production of CD discs, a thin layer of indium is used to strengthen them.

Indium is a diamagnetic metal; it slightly weakens external magnetic fields and is weakly repelled by magnets.
