Praseodymium oxide

Praseodymium oxide is a chemical compound of the rare-earth metal praseodymium and is usually present as praseodymium(III,IV) oxide (Pr₆O₁₁). It is a dark green to blackish-brown powder and is one of the most important industrial oxides among the rare earths.

It is primarily used to manufacture high-performance permanent magnets, which are indispensable in electric motors, wind turbines, robotics, and many electronic devices. Together with neodymium, it forms so-called NdPr oxide, which gives magnets their high strength.

In addition, praseodymium oxide is used in the glass and ceramics industry, where it produces color tones and absorbs UV radiation—for example in welding goggles or specialty glass. It also plays a role in catalysts and heat-resistant alloys.

Praseodymium oxide is a key material for high-performance permanent magnets, which are indispensable in electric motors and wind turbines. The strong dependence on Chinese supply chains regularly leads to price fluctuations. As demand rises in the long term due to e-mobility and renewable energy, temporary pullbacks continue to offer attractive opportunities to add to positions.

Praseodymium is not mined as a pure metal, but extracted from ores that contain multiple rare earths—primarily monazite and bastnäsite. The most important deposits are located in China, the USA (Mountain Pass), and Australia. After mining, the ores are chemically processed to dissolve the rare earths. This is followed by a complex separation of the elements, as they are chemically very similar. The extracted praseodymium is then further processed into praseodymium oxide (Pr₆O₁₁), which is used as a powder in magnets, glass, and alloys.
