To sponsor this element yourself, please contact Michelle Saxton, Dept. Praseodymium is soft, silvery, malleable, and ductile. It is somewhat resistant to corrosion in air, but does eventually oxidize. Praseodymium is used as a core material for carbon arcs used by the motion picture industry for studio lighting and projection.
Praseodymium oxide is among the most refractory substances known.
Praseodymium salts are also used to color glasses and enamels, and can be used to produce an intense and unusually clean yellow color in glass.
