INDIUM METAL

Indium is a Chemical Element with the symbol “In” and Atomic Number “49”. It is a post-transition metal that makes up 0.21 parts per million of the Earth’s crust. Very soft and malleable, Indium has a melting point higher than sodium and gallium, but lower than lithium and tin. Chemically, Indium is similar to gallium and thallium, and it is largely intermediate between the two in terms of its properties.

Indium is a minor component in zinc sulfide ores and is produced as a byproduct of zinc refinement. It is most notably used in the Semiconductor Industry, in low-melting-point metal alloys such as solder, in soft-metal high-vacuum seals, and in the production of transparent conductive coatings of Indium tin oxide (ITO) on the glass.

Indium has no biological role, though its compounds are somewhat toxic when injected into the bloodstream. Most occupational exposure is through ingestion, from which indium compounds are not absorbed well, and inhalation, from which they are moderately absorbed.
