Infobox references

Neodymium nitrate is an inorganic salt with the formula Nd(NO

3 * x(H
2O). It is typically encountered as the hexahydrate, Nd(NO

3 * 6H2O. It decomposes to NdONO
3 at elevated temperature.[5]

It is used in the extraction and purification of neodymium from its ores.[6]

## Production and Preparation

Neodymium(III) nitrate can be obtained by the action of nitric acid on neodymium(III) carbonate or other neodymium salts of weak acids.
