Indium is a relatively rare post-transition metal with a bright luster. It is also known for its very soft and malleable properties. In fact, it is so soft that the metal can even be cut with a knife. If drawn across a piece of paper, it will leave a mark like a lead pencil. Indium is silvery-white and resembles Tin in appearance. When bent, Indium emits a high-pitched “cry” like Tin.


Appearance:silvery lustrous gray

Melting point:429.7485 K (156.5985 °C, 313.8773 °F)

Boiling point:2345 K (2072 °C, 3762 °F)

Density (near r.t.):7.31 g/cm3




Indium foil is widely used in nuclear facilities to capture thermal neutrons, because it shows a high cross section of neutron capture reaction. Hence, it may be used in dosemeters to measure exposure. Indium foils were studied for simultaneous monitoring neutron and photon intensities in a reactor core.
