Indium is a rather rare metal in the Earth's crust, it is silvery-white, bright, shiny and very ductile. The metallic indium, like tin, emits a sharp screech when it is bent. An unusual property of Indium is to be radioactive, but very weakly so that it is not considered dangerous. Indium is mainly used in the preparation of semiconductors, alloys with a low melting point and for coating other metals. The most important compounds of Indium are those in which the metal behaves as trivalent.
