Neodymium Facts

Neodymium Facts
Neodymium (Nd) has an atomic number of sixty, and that same number of protons in the nucleus of one of its atoms. It is a bright silver member of the rare earth metals and a member of the lanthanides group.
Interesting Neodymium Facts:
Austrian scientist Carl Gustav von Weisbach discovered neodymium at the same time that he discovered praseodymium.
He had been studying the residue isolated by Mosander several years before when he made the discovery of both elements by fractional crystallization.
Despite being a rare earth element and never being found in its free form in nature, neodymium is as prevalent in the Earth's crust as nickel, copper, and cobalt.
It is most often found as a component in monazite and bastnasite minerals.
Neodymium's concentration is about thirty-eight milligrams per kilogram in the crust, which is second only to cerium for abundance of the rare earth elements.
As a lanthanide, neodymium is present in mischmetal, a naturally occurring conglomerate made up of several lanthanides at varying concentrations.
Neodymium is one of the more reactive of the rare earth metals, so it quickly begins to oxidize in air.
There are five naturally occurring stable isotopes of neodymium.
The most abundant of these stable isotopes is Nd-142 at a concentration of almost thirty percent of neodymium available.
Two of neodymium's radioactive isotopes, Nd-144 and Nd-150, are also found in nature.
There are an additional twenty-nine radioactive isotopes of neodymium, but the most stable are the two that are found naturally occurring.
The current reserves of neodymium are believed to be around eight million tons, with around seven thousand tons produced each year.
While neodymium's chief use was as a reddish-purple pigment for glass and ceramics, it has other applications in cryocoolers and as a fertilizer.
Neodymium, when alloyed with iron and boron, produces the strongest permanent magnets known to exist.
