CAS 7440-74-6

Indium

Description:

Indium is a post-transition metal with the chemical symbol "In" and the CAS number 7440-74-6. It is characterized by its silvery-white appearance and is relatively soft, malleable, and ductile, allowing it to be easily shaped and formed. Indium has a low melting point compared to many metals, which makes it useful in various applications, including soldering and electronics. It exhibits a unique property of expanding upon solidification, which is rare among metals. Indium is primarily found in zinc ores and is often extracted as a byproduct of zinc refining. Chemically, it is known to have a +1 and +3 oxidation state, with the +3 state being more stable in compounds. Indium is non-toxic and has applications in the production of indium tin oxide (ITO), which is widely used in touch screens and flat-panel displays. Additionally, it plays a role in the development of certain alloys and is being researched for potential uses in solar cells and other advanced technologies.
