Neodymium | Chemical elements

Neodymium was discovered in 1885 (and isolated in 1925) by Carl Auer von Welsbach. Its name derives from the Greek words "neos" which means "new", and "didymos" which means "twin". Neodymium’s melting point is at 1010.0 °C (1283.15 K, 1850.0 °F) and its boiling point is at 3127.0 °C (3400.15 K, 5660.6 °F).

Top 10 interesting facts about Neodymium

  1. Neodymium is a soft and silvery metal.
  2. Neodymium is found in significant quantities in ore minerals monazite and bastnasite.
  3. Neodymium is not found naturally in metallic form but always mixed with other lanthanides.
  4. China is by far the largest producer of neodymium.
  5. Neodymium has five stable isotopes: 142-Nd (the most abundant), 143-Nd, 145-Nd, 146-Nd, and 148-Nd.
  6. Neodymium is used in cryocoolers due to its large heat capacity and in lasers as a gain media for infrared wavelengths.
  7. Neodymium is used as a fertilizer (among other Rare Earth element compounds), particularly in China.
  8. Neodymium is used in permanent magnets and they are the most powerful magnets known, therefore these magnets are used in microphones, loudspeakers, guitars, hard-disks etc.
  9. Neodymium is widely used in glass industry for glass coloration, glass for astronomical work, incandescent light bulbs, rear-view mirror in automobiles industry for reducing glares at night etc.
  10. Neodymium compounds are of low/moderate toxicity.
