Features of Indium Ingot
01.
Indium is a silver-gray, very soft, fusible metal. The melting temperature of 156.61 ℃. The boiling point of 2060 ℃. Relative density d7.30. Liquid indium can soak into glass and stick to surfaces it touches leaving black marks.

02.
Indium is weakly radioactive. Natural indium has two main isotopes, one is in-113, which is a stable nuclide, and the other is β-decay. Therefore, avoid direct contact as much as possible in use.
