INDIUM |

|
When heated above its melting point it ignites and burns with a violet flame. Indium is used in alloys with low melting and as a protective plate for the bearings and other metal surfaces. It can be used to form the corrosion-resistant mirror surface: when evaporated and allowed to deposit on the glass produces a mirror as good a quality as that of silver. It is very weakly radioactive, because its atoms decay (with a half-life of 4x1014 years of age more time universe) into atoms of tin. His radioactivity, for the reasons stated, is not dangerous. Indium is used in alloys with low melting point (low-melting alloys) and as a protective plate for bearings and other metal surfaces. Can be used to form the surface resistant to corrosion of the mirrors: when evaporated and allowed to deposit on the glass produces a mirror quality as good as that of silver. It is used for thin films (thin layers of materials), panels for liquid crystal display (LCD), photoconductors, germanium transistors, glass for touchscreen, bearings for jet engines, solar panels. The annual world production is about 600 tons.

Indium is a soft, ductile, manleable, and brilliant. And 'silver-white, and has a face-centered tetragonal structure. It is liquid over a wide temperature range (such as gallium), is stable in air and in water but dissolves in acids.
