Praseodymium Metal Pr Rare Earth Ndfeb Magnetic Material
Product Description
- A soft, malleable, ductile and highly magnetic silvery metal.
- Belongs to the lanthanide rare earth metals.
- Forms a flaky black oxide coating (Pr6O11) in air. Unlike many metal oxide layers, this one does not protect the metal from further oxidation.
- The pale green sesquioxide, Pr2O3, is not stable in air.
- Praseodymium reacts with water to form praseodymium hydroxide plus hydrogen gas.

Applications
- High-intensity permanent magnets, which are essential in electric motors and generators used in hybrid cars and wind turbines.
- Nickel metal hydride (NiMH) rechargeable batteries for hybrid automobiles. The negative electrode (cathode) in NiMH batteries is a mixture of metal hydrides – typically a rare earth misch metal hydride containing praseodymium, neodymium, lanthanum and cerium.
- An alloying agent with magnesium creating a high-strength metal for aircraft engines.
- Praseodymium is used to make specialised yellow glass goggles for glass blowers and welders. Praseodymium salts are used to colour glasses and enamels.
- Flame lighter flints use misch metal (a rare earth alloy) containing praseodymium to produce sparks by friction.
- Also used in the core of high-intensity carbon arc lights used by the film industry and in floodlighting.
- Colouring in ceramics.
