Industrial context.
Praseodymium is often sold with neodymium in an NdPr product and can contribute to permanent-magnet performance. A blend needs a specification for relative composition, impurities and acceptable variation.
Questions for a supplier.
Ask for the declared Nd:Pr basis and relevant impurity limits. Link the blend specification to the downstream alloy and finished magnet approval process.
