বিষয়ে Yttrium
Yttrium is a silvery-white, ductile transition metal almost always found with lanthanides in rare earth minerals. It was the first of several elements found near the Swedish village of Ytterby.
Uses & Applications
Red phosphors for displays and LEDs, YAG lasers, high-temperature superconductors, and spark plugs.
মজা কথা
Four elements are named after the tiny Swedish village of Ytterby: yttrium, ytterbium, terbium, and erbium.
