Indium

Indium

Indium is a soft, silvery metal that is stable and used in low-melting alloys for fire-sprinkler systems in shops and warehouses. Some semi-conductors and transistors are made of indium arsenide or indium antimonide. Indium has semiconductor uses in transistors, thermistors and photoconductors. It is also used to make low-temperature alloys; for example, an alloy of
