PRASEODYMIUM
(Pr)
MATERIAL
OVERVIEW
Praseodymium
was discovered in 1885 by the German chemist Carl F.
Auer von Welsbach. Praseodymium is a yellowish
metal that tarnishes easily. Praseodymium salts
are generally green in color. Praseodymium
liberates hydrogen when in contact with water. It is
soluble in
dilute acids, paramagnetic and is considered nontoxic.
ESPI produces a variety of finished praseodymium
products including rod, wire, foil, sheet, pieces and
powder. Due to praseodymium's sensitivity to
oxygen the finished product is packaged under dry
argon in sealed metal cans.
