Praseodymium: Strongest as a Team Player

In the periodic table, praseodymium is a lanthanide, a group that belongs to the rare earth elements. Praseodymium is a particularly effective additive in alloys and compounds, and its properties make it an important building block for the success of the energy transition.


Alongside wind power, electromobility is considered the key factor in the rising demand for rare earths.

Praseodymium’s Discovery Is Closely Linked to Neodymium

The discovery of praseodymium took place gradually over several decades. In 1841, the Swedish chemist Carl Gustav Mosander extracted the rare earth metal didym from cerite, a mixture of oxides of various lanthanides discovered at the beginning of the 19th century. The name didym was derived from the Greek word for twin and referred to its similarity to the element lanthanum, which was also separated from cerite earth. In 1874, however, the Swedish natural scientist Per Teodor Cleve discovered that didym is actually two elements, neodymium and praseodymium. However, it was not until 1885 that the Austrian chemist Carl Auer von Welsbach succeeded in separating them. The twin thus became another twin: praseodymium became the green twin (from Greek: prásinos = green) and neodymium (from neos, for new) became the “new twin” due to the green color of some of its compounds.

The Discoverer of Praseodymium

Born in Vienna in 1858, the chemist Carl Freiherr Auer von Welsbach is one of Austria’s most famous scientists. Von Welsbach achieved fame through his success as an entrepreneur and inventor, among other things. This discoverer of several rare earths conducted research in a laboratory in his own castle, among other places.


Praseodymium Has Paramagnetic Properties

In metallic form, praseodymium is soft, silvery-white, and reactive. It is somewhat more resistant to corrosion in air than europium or lanthanum, for example, but easily forms a green oxide layer. Like the other lanthanides, the rare earth metal is paramagnetic, which means that magnetic forces only develop when an external magnetic field is applied.

Areas of Application

Main Application: Permanent Magnets

In addition to many chemical and physical properties, neodymium, and praseodymium also share their most important area of application: permanent magnets. The strongest such magnets in the world are based on a neodymium-iron-boron alloy, to which a certain amount of praseodymium can be added. These NdFeB magnets are required for technologies such as electric motors, wind turbines, and MRI scanners, but are also used in everyday devices such as loudspeakers and headphones. Like its „twin“ neodymium, praseodymium is also used to color and decolorize glass. Solid-state lasers and alloys are further areas of application.

Permanent Magnets

Permanent magnets retain their magnetic force without external energy inputs. They are in great demand in areas that require high power density, such as electromobility and wind power. They are the driving force behind many environmentally friendly technologies.

Wind Power Technology

Wind turbines use generators to convert wind energy into electricity. Many of these generators use permanent magnets made from rare earths to make the systems powerful, easy to maintain, and quiet. Wind power technology will play a crucial role in a successful energy transition.

The beginnings of electromobility date back to the 19th century. Due to the fight against climate change, this technology is experiencing a renaissance and driving demand for powerful magnets that convert electricity into kinetic energy in electric motors.

A Sought-After Raw Material for Green Technologies

Praseodymium only occurs in nature in chemical compounds with other lanthanides, mainly in minerals such as bastnäsite and monazite. The largest deposits of rare earths are found in China, Vietnam, Brazil, and Russia. China is the world leader in the mining and processing of these critical raw materials.

The Bayan Obo deposit in China, Mountain Pass in the US, and Mt. Weld in Australia are currently important sources of praseodymium.

Permanent Magnets as Demand Drivers

Especially in combination with neodymium, praseodymium will continue to be a sought-after raw material for industry, as permanent magnets are considered a growth market due to their importance in increasingly important technologies such as electromobility and wind power. The German Mineral Resources Agency DERA forecasts that by 2040, the demand for neodymium and praseodymium could increase to up to 227% of primary production of the elements in 2018. Due to the high concentration of countries that produce and process praseodymium, there is a prospective supply risk given the massive increase in demand.

  • China has market power over rare earths.
  • Europe and the US are striving to establish their own value chains.
