歷史
Neodymium was first identified in 1885, in Vienna, by the Austrian chemist Carl Auer von Welsbach.

It was discovered in didymium, a substance incorrectly said by Carl Gustav Mosander to be a new element in 1841.

Pure neodymium metal was isolated in 1925.

應用
Neodymium is used to make specialized goggles for glass blowers.

Neodymium magnets appear in products such as microphones, professional loudspeakers, in-ear headphones, guitar and bass guitar pick-ups and computer hard disks.

Glass containing neodymium can be used as a laser material to produce coherent light.
Neodymium is considered to be moderately toxic
