Wandering through the references to indium metal on the internet, I sometimes see it referred to as, "that 'rare' metal." But is it really so rare? I recently talked to my colleague, Claire Miko, Director, Metals and Chemicals for Indium Corporation and asked if the reports of the rarity of the ...
Indium is a chemical element with 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 produced mainly from residues generated during zinc ore processing. It was named after the indigo line in its atomic spectrum. It was named after the indigo line in its atomic spectrum. The first large-scale application for indium was as a coating for bearings in high-performance aircraft engines during World War II.
