Praseodymium Oxide (Pr6O11) Powder

Product Information

Praseodymium(III,IV) Oxide is a highly insoluble thermally stable Praseodymium source suitable for glass, optic and ceramic applications. Praseodymium(III,IV) Oxide is generally immediHigh Purity (99.999%) Praseodymium(III,IV) Oxide (Pr₂O₃) Powderately available in most volumes. Ultra high purity and high purity compositions improve both optical quality and usefulness as scientific standards. Nanoscale elemental powders and suspensions, as alternative high surface area forms, may be considered. Praseodymium is highly valued in glass and ceramic production as a bright yellow pigment because of its optimum reflectance at 560 nm. Oxide compounds are not conductive to electricity. However, certain perovskite structured oxides are electronically conductive finding application in the cathode of solid oxide fuel cells and oxygen generation systems. Rare Earth oxide compounds are basic anhydrides and can therefore react with acids and with strong reducing agents in redox reactions. They are compounds containing at least one oxygen anion and one metallic cation. They are typically insoluble in aqueous solutions (water) and extremely stable making them useful in ceramic structures as simple as producing clay bowls to advanced electronics and in light weight structural components in aerospace and electrochemical applications such as fuel cells in which they exhibit ionic conductivity. Praseodymium oxide is also available in pellets, pieces, sputtering targets, tablets, and nanopowder.."

Chemical Composition

Physical Properties – Praseodymium Oxide (Pr₆O₁₁) Powder

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.

Praseodymium Oxide Applications

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

Praseodymium oxide is used to make ceramic glaze, praseodymium yellow and permanent magnets, petroleum catalytic cracking, abrasive polishing, optical fiber fields, and used to make cameras, microscopes, various optical glass components, and optical fibers. It also has certain uses in the electronic ceramic industry and catalyst preparation.
