Praseodymium Metal Pr CAS 7440-10-0 For Permanent Magnet Material

Praseodymium metal is a rare earth element with an atomic number of 59 and a silver-white and yellow-green luster. Praseodymium derives its name from the Greek word meaning "green", because of the green color of its oxide. Praseodymium has strong corrosion resistance in the air, but long-term exposure will produce fragile green oxides, so it needs to be stored in mineral oil or sealed plastics.
Praseodymium is widely used in many fields. In petrochemical industry, praseodymium, as a catalyst component, can improve the activity and stability of petroleum cracking catalysts. In the field of magnetic materials, praseodymium can be mixed with other rare earth elements to make high magnetic energy product permanent magnet materials, which are widely used in electronic equipment such as motors and generators. In addition, praseodymium is also an important component of electronic materials, used to manufacture high-tech products such as leds and detectors. In the metallurgical industry, praseodymium can improve the hardness and wear resistance of steel and improve its processability.

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.

Used

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.
