Neodymium(III) fluoride is an inorganic chemical compound of neodymium and fluorine with the formula NdF3. It is a purplish pink colored solid with a high melting point. Like other lanthanide fluorides it is highly insoluble in water which allows it to be synthesised from aqueous neodymium nitrate via a reaction with hydrofluoric acid, from which it precipitates as a hydrate:[1]

Nd(NO3)3(aq) \+ 3 HF → NdF3•½H2O + 3 HNO3

Anhydrous material may be obtained by the simple drying of the hydrate, in contrast to the hydrates of other neodymium halides, which form mixed oxyhalides if heated.[1]
