Infobox references

Gadolinium(III) nitrate is an inorganic compound of gadolinium. This salt is used as a water-soluble neutron poison in nuclear reactors.[1] Gadolinium nitrate, like all nitrate salts, is an oxidizing agent.

The most common form of this substance is hexahydrate Gd(NO3)3•6H2O with molecular weight 451.36 g/mol and CAS Number: 19598-90-4.[1]

## Use

Gadolinium nitrate was used at the Savannah River Site heavy water nuclear reactors and had to be separated from the heavy water for storage or reuse.[2][3] The Canadian CANDU reactor, a pressurized heavy water reactor, also uses gadolinium nitrate as a water-soluble neutron poison in heavy water.

Gadolinium nitrate is also used as a raw material in the production of other gadolinium compounds, for production of specialty glasses and ceramics and as a phosphor.
