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

Use[edit]

Gadolinium nitrate was used at the Savannah River Site heavy water nuclear reactors and has 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.
