- noun a soft silvery metal, used in alloys, transistors and electroplating
- A lustrous silvery-white metallic chemical element whose atomic number is 49. It is soft, malleable, ductile, and when bent emits a characteristic metallic cry. It has over 30 known isotopes, of which one is stable. Indium has many applications, including its uses in semiconductor devices, low-melting point alloys, including some which are liquid at room temperature, in photoconductors, in nuclear reactor control rods, in bearings and gaskets that work effectively at cryogenic temperatures, and it can be plated onto another metal to form corrosion-resistant mirrors. Its chemical symbol is In.
