Top 10 interesting facts about Praseodymium

  • Praseodymium was discovered in 1885 by Carl Auer von Welsbach. Its name derives from the Greek words "prasios" which means "green", and "didymos" which means "twin".
  • Praseodymium's melting point is at 935.0 C (1208.15 K, 1715.0 F) and its boiling point is at 3127.0 C (3400.15 K, 5660.6 F).
  • Praseodymium is soft, silvery, malleable, and ductile metal.
  • Praseodymium is not found freely in nature due to its highly reactive properties.
  • Praseodymium is stored under mineral oil.
  • Praseodymium has only one stable isotope, 141-Pr.
  • Praseodymium is found in small quantities in Earth's crust in monazite and bastnasite minerals.
  • Praseodymium is used in high-power magnets production, in a special alloy for high-strength metals for aircraft industry, in studio and projector lights, and in glass industry to create yellow glass.
  • Praseodymium is not considered to be a toxic metal.
  • Praseodymium doesn't have any biological role in living organisms.
