Dysprosium Nitrate Hydrate Dy(NO3)3 5H2O CAS 10031-49-9
product detail
Name: Dysprosium nitrate, Gadolinium nitrate hydrate Molecular formula: Dy(NO3)3·5H2O
CAS: 10031-49-9 Molecular weight: 438.59
Description: Dysprosium nitrate is a white crystal, soluble in water and alcohol, and deliquescent in humid air. The preparation method is to put dysprosium oxide into 2mol / L nitric acid, heat the reaction until the solution is complete, then evaporate part of the solvent under reduced pressure, cool down, precipitate and crystallize, and filter to obtain dysprosium nitrate pentahydrate. Generally, it is slightly harmful to water body. Do not contact undiluted or large amount of products with groundwater, water channel or sewage system.
