Detailed Product Description

Name:	Praseodymium Metal Pr Rare Earth Ndfeb Magnetic Material	Product Type:	Rare Earth Metal
Content(percent):	99%	Application:	Ndfeb Magnetic Material
Atomic Symbol:	Pr	Atomic Number:	59
Element Category:	Lanthanide Metal	Atomic Weight:	140.90765

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.

Specification

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.
