Praseodymium Metal Pr CAS 7440-10-0 For Permanent Magnet Material
Name: Praseodymium metal Molecular formula: Pr
CAS: 7440-10-0 Molecular weight: 140.91
Description: Praseodymium can be made into various forms: Praseodymium foil, Praseodymium powder and Praseodymium rod. The praseodymium content in the earth's crust is about 5.53 × 10-4%, mainly in monazite and bastnaesite, and the fission products also contain praseodymium. The metal praseodymium is silver white metal, soft and malleable. Its corrosion resistance in the air is stronger than that of lanthanum, cerium, neodymium and europium. However, when exposed to the air, it will produce a layer of fragile green oxide. Praseodymium slowly forms a green fragile oxide layer in the air. Metal praseodymium is generally produced by electrolysis of praseodymium fluoride and praseodymium oxide mixed molten salt.

Use: Praseodymium alone as a permanent magnet material is not outstanding, but it is an excellent synergistic element to improve the magnetic properties. Whether it is the first generation of samarium cobalt permanent magnet or the third generation of NdFeB permanent magnet, adding a proper amount of praseodymium can effectively improve the performance of the permanent magnet. The addition of praseodymium can also improve the oxidation resistance (air corrosion resistance) and mechanical properties of magnets, which have been widely used in various electronic devices and motors.
