Terbium Nitrate Hydrate Tb(NO3)3 5H2O CAS 57584-27-7 For Fluorescent Compounds

Terbium nitrate is a colorless crystalline solid, soluble in water, ethanol, acetone and esters. It has high thermal stability in air, but will decompose at high temperatures. Terbium nitrate plays an important role in the fractional crystallization separation of rare earth elements, and can also be used to prepare rare earth element complexes. In addition, it has a wide range of applications in optical and magnetic materials, and can be used to manufacture phosphors, optical glasses, ceramics and magnetic materials. However, terbium nitrate is corrosive and toxic and requires appropriate protective measures and compliance with relevant safety regulations when used. Waste needs to be handled in accordance with local regulations to ensure that it does not pose a hazard to the environment.

product detail

Name: Terbium nitrate, Terbium nitrate hydrate Molecular formula: Tb(NO3)3·5H2O

CAS: 57584-27-7 Molecular weight: 435.02

Description: Terbium nitrate is a colorless monoclinic crystal, which decomposes at high temperature and can be dissolved in water, ethanol, acetone and esters. It can be extracted into organic solvent phase by Tributyl phosphate. Its anhydrous salt is easily soluble in anhydrous amine, nitrile and other polar organic solvents. The preparation method is to dissolve terbium metal in nitric acid, or to react terbium oxide with nitric acid, and to crystallize terbium nitrate hydrate from aqueous solution.
