Indium is a rare element that is one of the heavy metals. It is very ductile, has very low hardness and has a low melting point. At high temperatures, indium metal reacts with many nonmetals. It is stable in air at room temperature. Indium does not dissolve in hot water and most organic acids. It is also not attacked by salt water. However, the metal is readily soluble in mineral acids (nitric acid or sulfuric acid).
Indium is now mainly processed into indium tin oxide. This semi-conductive transparent substance is used in the manufacture of flat panel displays and touch screens. Indium is also used as an alloy component. It can be alloyed with bismuth, tin, cadmium and lead. Alloys of gallium and indium are used in the manufacture of high-temperature thermometers. Alloys based on indium, copper and manganese are suitable for the construction of coils and transformers.
