Praseodymium metal is widely used in the manufacture of permanent magnets. By using inexpensive praseodymium neodymium metal instead of pure neodymium metal to manufacture permanent magnet materials, the oxidation resistance and mechanical properties of magnets can be significantly improved, making them machinable into various shapes of magnets and widely used in various electronic devices and motors.
Praseodymium metal is also used in petroleum catalytic cracking. Adding praseodymium neodymium rich material to Y-type zeolite molecular sieve to prepare petroleum cracking catalyst can improve the activity, selectivity, and stability of the catalyst.
Praseodymium metal is also used in the manufacture of special alloys and special glasses, as well as as as a pigment for pottery. It can coexist with neodymium as a purifying and modifying agent for metal materials.
In addition, the use of praseodymium metal in the field of optical fibers is becoming increasingly widespread, demonstrating its potential value in modern technology.
