Mineral Species containing Indium (In)

Element Properties, Isotopic Compositions for Indium

**Indium (In) Element Properties**
Atomic Mass	114.82
Atomic Number	49
Name Origins	Named after the indigo line in its spectrum.
Year Discovered	1863
Discovery Credits	Discovered by Ferdinand Reich and Hieronymous Richter at Frieberg, Germany.
Remarks	Soft, silvery-white metal. Stable in air and with water, dissolves in acids. Used in low melting alloys in safety devices. Semiconductor uses as InAs and InSb in transistors, thermistors, etc. Diagnostic tests: There are no simple chemical tests for indium. Atomic Absorption Spectroscopy is used for quantitative analysis and Energy Dispersive Analysis of X-rays (EDAX) is used for qualitative analysis. The flame test for Indium may show a blue color.
