Indium sputtering target is used to coat the bearings of high-speed motors because it can evenly distribute the lubricant. Indium targets are also used in thin film deposition, decoration, semiconductors, displays, LED and photovoltaic devices, functional coatings, and other optical information storage space industries, glass coating industries such as automotive glass and architectural glass, and optical communications.
Indium is also used to make other electrical components such as rectifiers, thermistors and photoconductors. Indium can be used to make mirrors that have the same reflectivity as silver mirrors but will not fade. Indium is also used to make low melting point alloys. The alloy of 24% indium and 76% gallium is liquid at room temperature.
