Abstract Preparation of “NaREF4” compounds (RE = La-Lu, Y) from rare earth nitrates dissolved in molten NaNO3 has been studied at 350°C. Two-fold excess of sodium fluoride (NaF) was used as fluorinating agent. Hexagonal NaREF4 (RE = Pr-Lu, Y) phases isotypic with β-NaYF4 have been prepared. A mixture of CeF3 and NaCeF4 was obtained in cerium system, while only LaF3 phase was formed in lanthanum system.
