Indium (In) Metal

Indium (In) Metal is a soft, ductile, malleable, luster-full silvery-white metal. Indium is one of the least abundant minerals on Earth. While it has been found uncombined naturally, it is usually associated with zinc, iron, lead, and copper ores. It retains many physical properties at cryogenic temperatures and acts like tin, emitting a high-pitched sound when bent. It is thermally and electrically conductive. It is found in many fusible alloys. Indium metal also can stick to glass.

Purity: 99.9 – 99.999%
Typical Applications

The major application of indium is used to make indium tin oxide (ITO). This compound is used in touch screens, flat screen TVs, and solar panels. It is used to give a mirror finish to windows of tall buildings and as a protective film on welders’ goggles. Other indium compounds are semiconductors used in transistors and microchips. Indium is used to manufacture equipment operating in harsh environments, e.g., space and cryogenics, and also has been used to coat ball bearings in airplanes, Formula 1 racing cars, and in fire-sprinkler systems.
