Neodymium nitrate explained

Neodymium nitrate is an inorganic compound with the formula . It is typically encountered as the hexahydrate, Nd(NO3)3·6H2O, which is more accurately formulated as [Nd(NO<sub>3</sub>)<sub>3</sub>(H<sub>2</sub>O)<sub>4</sub>].2H2O to reflect the crystal structure.[1] It decomposes to NdONO3 at elevated temperature.[2]

It is used in the extraction and purification of neodymium from its ores.[3]
