Gadolinium(III) fluoride is an inorganic compound with a chemical formula GdF₃.

Preparation

Gadolinium(III) fluoride can be prepared by heating gadolinium oxide and ammonium bifluoride. The reaction involves two steps:^[1]^[2]

Gd₂O₃ + 6 NH₄HF₂ → 2 NH₄GdF₄ + 4 NH₄F + 3 H₂O

NH₄GdF₄ → GdF₃ + NH₃ + HF

Alternatively, reacting gadolinium chloride with hydrofluoric acid and adding hot water produces GdF₃·xH₂O (x＝0.53). Anhydrous gadolinium(III) fluoride can then be produced by heating the hydrate with ammonium bifluoride; without the bifluoride, GdOF is formed instead.^[3]

GdCl₃ + 3 HF + x H₂O → GdF₃·xH₂O + 3 HCl

Properties

Gadolinium(III) fluoride is a white solid that is insoluble in water. It has an orthorhombic crystal structure with the space group Pnma (space group no. 62).^[4]

Uses

Gadolinium(III) fluoride is used to produce fluoride glasses.^[5]
