The element neodymium and the lanthanide praseodymium are a part of the rare earth group that sits at the bottom of the periodic table. They are called “rare earth” because they’re not commonly found in nature, but they play an important role in the development of many hi-tech products.
Neodymium (Nd) and Praseodymium, together with the lanthanides terbium and dysprosium are essential for the development of many technologies such as batteries, magnets, photovoltaics, and energy-saving devices. The demand for these elements is expected to increase as the use of electric cars, wind turbines, and solar panels increases.
About Neodymium & Praseodymium
Neodymium is a rare earth metal that is extracted from the mineral carbonatites in the rock bastnasite. The deposits of this rare earth are mainly in China and the USA. It is an essential component in the construction of a strong permanent magnet, used in loudspeakers and computer hard drives to make them smaller and more efficient.
It is also a key component in making a special kind of glass, used in goggles to protect glassblowers and welding technicians. It is also used in X-ray and MRI scanning systems, and as a lens material for cameras and telescopes.
Praseodymium is an aliovalent metal that can exist in 3 + and 4+ oxidation states in its single oxide form as well as in a solid solution with ceria. The resulting ceria-praseodymium complex has been found to have improved mobility of oxygen anions, which is useful for a variety of oxidation processes.
