Nimen alkuperä: indicum
Nimen tarkoitus: a Latin word meaning indigo blue: spectral stripes of indium are bright blue
- its primary application is to form transparent electrodes from indium tin oxide in liquid crystal displays
- is also used for making particularly low melting point alloys, and is a component in some lead- free solders
- radioactive indium-111 is used in nuclear medicine as an imaging agent to follow the movement of leukocytes in the body
- pure indium in metal form is considered non-toxic by most sources
- the first large-scale application for indium was as a coating for bearings in high-performance aircraft engines during World War II
