Not necessary for life.
Named from the Greek words meaning “new twin,” neodymium is a silvery-yellow metal. It is a very active metal, reacting with air, water and most acids. Neodymium is used in alloys for powerful permanent magnets, lasers, and to color glazes and glass. It colors glass many shades of red and purple, and also is used in didymium glass for welder’s goggles. Mischmetal contains 18% neodymium. Neodymium also is used as spectral filters in astronomical work, as well as filters in tanning beds, where it filters out infrared rays, while allowing the ultraviolet tanning rays through.
Neodymium has no known biological use.
