Gadolinium(III) fluoride is aninorganic compound with a chemical formula GdF3.
Gadolinium(III) fluoride can be prepared by heatinggadolinium oxide andammonium bifluoride. The reaction involves two steps:[1][2]
Alternatively, reactinggadolinium chloride withhydrofluoric 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]
Gadolinium(III) fluoride is a white solid that is insoluble in water. It has an orthorhombic crystal structure with thespace group Pnma (space group no. 62).[4]
Gadolinium(III) fluoride is used to producefluoride glasses.[5]
