Uses and properties
The symbol used here is the Japanese kanji character ‘hon’. It means ‘origin’. Indium is named after the bright indigo line in its spectrum. The Japanese discovered that cotton was a difficult fabric to dye, except with indigo. So, indigo dye was widely used to colour cotton throughout the Edo period (1603–1867).AppearanceA soft, silvery metal that is stable in air and water.

Uses
Most indium is used to make indium tin oxide (ITO), which is an important part of touch screens, flatscreen TVs and solar panels. This is because it conducts electricity, bonds strongly to glass and is transparent.Indium nitride, phosphide and antimonide are semiconductors used in transistors and microchips.

Indium metal sticks to glass and can be used to give a mirror finish to windows of tall buildings, and as a protective film on welders’ goggles. It has also been used to coat ball bearings in Formula 1 racing cars because of its low friction.

An indium alloy has been used for fire-sprinkler systems in shops and warehouses because of its low melting point.Biological roleIndium has no known biological role. It is toxic if more than a few milligrams are consumed and can affect the development of an embryo or foetus.

Natural abundance
Indium is one of the least abundant minerals on Earth. It has been found uncombined in nature, but typically it is found associated with zinc minerals and iron, lead and copper ores. It is commercially produced as a by-product of zinc refining.
