Praseodymium Oxide Pr6O11 CAS 12037-29-5 For Yellow pigment

Praseodymium oxide is a rare earth oxide, dark green to dark brown powder at room temperature, with high thermal stability and chemical stability. It is insoluble in water, but can dissolve in acid and form trivalent salts, good electrical conductivity. In industry, praseodymium oxide is widely used in ceramics, glass, rare earth permanent magnet, rare earth polishing powder and other fields. As an additive of ceramic glaze and pigment, it can improve the color and performance of ceramics. The addition of praseodymium oxide to glass can make green glass, which is used for decoration and imitation gemstone production. In addition, praseodymium oxide is also used in the production of high-tech materials such as petroleum cracking catalysts and rare earth permanent magnets.

Name: Praseodymium oxide

CAS: 12037-29-5

Molecular formula: Pr6O11

Molecular weight: 1021.44

Description

The rare earth chloride solution was leached from Monazite Concentrate by alkali solution, dephosphorization and dilute hydrochloric acid. The rare earth mixture can be divided into three groups: light, medium and heavy rare earth by P204-HCl system extraction. The light rare earth in La-Nd group (containing medium rare earth Sm2O3 < 1%) was separated according to the oxalate precipitation sequence: Samarium, Neodymium, Praseodymium, Cerium and Lanthanum. The oxalate can be precipitated into soluble complex and then precipitated to separate it. After drying, Praseodymium oxide can be obtained by burning at 1000 ℃.
