Abstract
The local structure in molten YF3-LiF and LaF3-LiF binaries has been investigated by NMR and EXAFS spectroscopy. For YF3-LiF, the high-temperature 19F and 7Li NMR spectra have been recorded in situ in the molten state for compositions ranging from pure LiF to pure YF3-LiF. The LaF3 system has been studied by 19F and 139La NMR and EXAFS spectroscopy at the LIII edge of La. The local environment around the La3+ in the molten state does not depend on the composition, while 19F chemical shift evolution confirms the progressive formation of bridged species. © 2004 Académie des sciences.
