Overview
Praseodymium is a soft, silvery rare earth metal used to impart magnetic and optical properties to materials.
Properties
It commonly forms +3 ions, contributes to strong permanent magnets when alloyed and colors glass and ceramics.
Occurrence and Uses
Praseodymium is used in high strength magnets, specialized glass, aircraft engines and lighting applications.
Isotopes and Safety
Stable isotope Pr 141 is natural; praseodymium compounds are handled with routine industrial precautions.
