Neodymium: The Essential Element
Neodymium (Nd) is a chemical element found in the lanthanide family of elements, which gives it a range of unique characteristics. It is often referred to as a ‘rare earth element’ due to its scarcity.
This element is essential in a range of modern applications, some of which can be found in everyday items such as smartphones and computers. Neodymium has widespread uses in industry, medicine, science, research and more.
History and Discovery of Neodymium
Neodymium was discovered in 1885 by the Austrian chemist Carl Auer von Welsbach. It was identified as a new element through a method of fractional crystallization. Auer von Welsbach had been searching for elements which could be used in low-temperature nuclear reactors, and was surprised to find neodymium in the stone he was investigating.
Despite not initially being successful in his mission, Auer von Welsbach was awarded the 1923 Nobel Prize in Chemistry for his brilliant discovery. The discovery of neodymium has also made it possible to create a range of modern technologies, and it is now used in a variety of everyday items.
