Description of Praseodymium Oxide

Praseodymium oxide, also known as praseodymia, is a dark brown powder which is insoluble in water and only soluble in strong acid. Praseodymium oxide is stable under normal temperatures and pressures.

It is a rare earth oxide compound, which is a basic anhydride and can therefore react with acids and with strong reducing agents in redox reactions. Rare earth oxide compounds contain at least one oxygen anion and one metallic cation. They are typically insoluble in aqueous solutions (water) and extremely stable, which make them useful in ceramic structures. For this reason, Praseodymium oxide has a wide range of applications from producing clay bowls to advanced electronics. Praseodymium oxide is also useful in lightweight structural components in aerospace and electrochemical applications such as fuel cells due to its ionic conductivity.

Production Method

1. Monazite concentrates go through the alkali solution, phosphorus moving out, leaching of diluted hydrochloric acid to get the rare earth chloride solvent; 
2. Next extract with P2O4-kerosene-HCl-ReCl system to divide it into three groups which are light, middle and heavy rare earth; 
3. Then raffinate La-Nd light rare earth is divided according to the oxalate sediment sequence which is samarium-neodymium(Nd)-praseodymium-cerium-lanthanum; 
4. Lastly, oxalate sediment could produce soluble complex and then separate and dry to get the Praseodymium oxide(Pr6O11) at 1000℃.

Chemical equation: 3Pr2(C2O4)3→Pr6O11+7CO2+11CO.


Applications of Praseodymium Oxide

• Component of didymium glass which is a colorant for welder's goggles, also as an important additive of Praseodymium yellow pigments.
• Used to make praseodymium yellow, when used in ceramics.
• Used as a coloring agent in the glass industry.
• If applied in metallurgical industry, praseodymium oxide can be used as a material for producing Praseodymium, Samarium (Sm), Cobalt (Co) and other permanent magnet alloys.
