Praseodymium Nitrate Hydrate Pr(NO3)3 6H2O Purity 99.99% CAS 15878-77-0
product detail
Name: Praseodymium nitrate, Praseodymium nitrate hydrate Molecular formula: Pr(NO3)3·6H2O
CAS: 15878-77-0 Molecular weight: 435.01
Description: Praseodymium nitrate is triclinic crystal. It is easy to dissolve in polar solvents such as anhydrous amine, ethanol, ether and acetonitrile. The preparation method of praseodymium nitrate is to heat praseodymium oxide to high temperature and then dissolve it in nitric acid, and then evaporate and concentrate it to obtain five or six water salts.
