More info

Praseodymium (Pr) Metal is a chemical element with the symbol Pr and atomic number 59 that belongs to the lanthanide series of elements. It is a soft malleable, silvery-yellow metal. It reacts slowly with oxygen when exposed to air it forms a green oxide that doesn't protect it from further oxidation. It's more immune to corrosion in the air than the opposite rare metals, but it still must be stored under oil or coated with plastic. It reacts rapidly with water. HM stocks a wide variety of rare earth materials for use in electronics, petrochemicals, metallurgy, machinery, energy, environmental protection, agriculture, and other fields. We also offer pure metals and compounds for R&D applications.
