Praseodymium Overview
Name Origin
Greek: prasios and didymos (green twin); from its green salts.
Symbol
Pr (Praseodymium)Description
Silvery white, moderately soft, malleable, ductile metal.
Discovery
Discovered By: C.F. Aver von Welsbach
Year: 1885
Location: Austria
Sources
Obtained from same salts as neodymium.
Uses
Used with neodymium to make lenses for glass maker's goggles since it filters out the yellow light present in glass blowing. Alloyed with magnesium creates a high-strength metal used in aircraft engines. Makes up 5% of Mich metal.
State at 20 °C
Solid
