Praseodymium comes from the Greek word for "green". The crystal structure of the cell is a hexagonal cell. Praseodymium is more resistant to corrosion in the air than lanthanum, cerium, neodymium and europium. When exposed to air,  praseodymium produces a brittle layer of green oxide. Pure praseodymium must be preserved in mineral oil or sealed plastic. One of the uses for praseodymium is in the catalytic cracking of petroleum. The activity, selectivity and stability of petroleum cracking catalyst can be improved by adding the enrichment of praseodymium and neodymium into the Y zeolite molecular sieve. Praseodymium, like other rare earth elements, has low toxicity and is not necessary for living things.

Application Field

  • Praseodymium can be used as a catalyst in the petrochemical industry.
  • Rare earth permanent magnet materials are the most popular rare earth application field. Praseodymium alone as a permanent magnet material is not outstanding, but it is an excellent synergistic element that can improve the magnetic properties. Whether the first generation of rare earth permanent magnet material samarium cobalt permanent magnet alloy or the third generation of rare earth permanent magnet material NdFeB, adding the appropriate amount of praseodymium can effectively improve and improve the performance of permanent magnet materials.
  • Praseodymium is also used for grinding and polishing materials.
  • Praseodymium in the field of optical fiber is more and more widely used, has developed the praseodymium doped fiber amplifier (PDFA) in the 1300~1360nm spectrum amplifier effect, the technology is becoming mature.
