Praseodymium is a chemical element with the symbol Pr and atomic number 59.

It is the third member of the lanthanide series and is considered one of the rare earth metals. It is a soft, silvery, malleable, and ductile metal valued for its magnetic, electrical, chemical, and optical properties. Natural praseodymium is so reactive that pure praseodymium metal slowly forms a green oxide coating when exposed to air.

It has various applications in different fields. For example, praseodymium is used with neodymium to make high-power magnets. It can be used in alloys with magnesium to produce high-strength metals for aircraft engines. It is also used to tint different types of glasses.

Symbol: Pr

Atomic number: 59

Atomic weight: 140.90766

Element category: lanthanide

Application of praseodymium

Rare earth magnets, lasers, core material for carbon arc lighting, colorant in glasses and enamels, additive in didymium glass used in welding goggles, ferrocerium fire steel (flint) products. It also can be used as an alloying agent with magnesium to create high-strength metals that are used in aircraft engines.

Edgetech Industries provides various praseodymium metal products including:

Irregular: lump, chunk, granules.

Solid: Ingot, rod, block, plate, sputtering target, and other customized parts.

Irregular Praseodymium Metal

We provide lump, chunk, granules for irregular praseodymium metal.

Size range for each praseodymium metal product:

Lump & Chunk: 1-100mm

Granules: 1-30mm

Shaped Praseodymium Metal

We provide ingot, block, rod, and sputtering targets for shaped praseodymium metal. Foils and sheets are produced by the rolling process. Wherein praseodymium (Pr), samarium (Sm), and Lutetium (Lu) are difficult processes due to the crystal structure. They cannot be rolled; we’ll adjust the process according to user requirements. Thin products are not available for these elements.

Praseodymium Metal Rod

Size range for each praseodymium metal product:

Rod, Cylinder: 5-10mm diameter x 10mm length min

Round praseodymium sputtering target or disc:

Diameter: <18”, Thickness: >0.04”

Rectangular praseodymium sputtering target:

Length: <36”, Width: <12”, Thickness: >0.08”

Block & Ingot: Customized


Praseodymium Oxide

Praseodymium oxide, also known as praseodymia, is a dark brown powder that is insoluble in water and only soluble in strong acids. Praseodymium oxide is stable at normal temperature and pressure. Due to its ionic conductivity, it can be used in lightweight structural components in aerospace and electrochemical applications such as fuel cells. We supply high-purity Pr6O11 in powder, granules, pellets, sputtering targets, and other custom forms.
