Praseodymium in permanent magnets
Praseodymium can partly supplement neodymium in the magnetic phase. However, an application, type designation or strong magnetic attraction does not establish either the praseodymium content or a particular NdPr composition.
Role in the magnet
Understand praseodymium’s role in the material system
A specific proportion cannot be inferred from appearance, application or magnet grade.
Function
Praseodymium can partly supplement neodymium in the magnetic phase. However, an application, type designation or strong magnetic attraction does not establish either the praseodymium content or a particular NdPr composition.
Material boundary
Praseodymium metal, oxides and NdPr alloys must not be equated with a finished magnet.
Evidence
Batch documentation, manufacturer data or suitable analysis must relate to the specific lot.
Weight
Total magnet mass, assembly mass and the mass of the individual element are different quantities.
Purchase assessment
Form, origin, condition, net magnet mass and potential recovery route are assessed first.
