Chemical compound

Gadolinium(III) nitrate is an inorganic compound of gadolinium with the formula Gd(NO3)3. A hydrate with the formula [Gd(NO3)3(H2O)4]·2H2O exists.[2] This salt is used as a water-soluble neutron poison in nuclear reactors.[3] Gadolinium nitrate, like all nitrate salts, is an oxidizing agent.

Use

[edit]

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.[4][5] 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.
