Praseodymium: Shining Bright into the Future
Praseodymium, often abbreviated as Pr, is one of the rarest metals on Earth. It is silvery-white in color and is found in trace amounts in the minerals monazite and bastnasite. This remarkable metal is critical in modern society, as it is used in everything from catalytic converters to computer keyboards.
It is also essential for the production of many other compounds. Praseodymium is among the most important elements on the periodic table and its significance is only growing.
History and Discovery of Praseodymium
Praseodymium was discovered in 1841 by Austrian chemist Carl Auer von Welsbach. He was experimenting with a mixture of yttrium and cerium oxides when he noticed an element present in his product. He called this element praseodymium, which is derived from the Greek word ‘prasinos’, meaning ‘green’.
In the years since, more scientists have researched and discovered its properties.
