Study of the composition and processes of dehydration of hydrated neodymium fluorides

  • 29 Accesses

Conclusions

  1. 1.

    The conditions of production of amorphous and crystalline neodymium fluorides were determined.

  2. 2.

    Mono- and polyhydrates of neodymium fluoride were detected, and the existence of a number of other hydrated neodymium fluorides was shown.

  3. 3.

    The dehydration of hydrated neodymium fluorides proceeds without hydrolysis through the steps NdF3(1−0.5)H2O → NdF3·0.25H2O → NdF3·0.13H2O → NdF3.

  4. 4.

    The stepwise nature of the dehydration of NdF3(1−0.5)H2O is evidently due to the existence of water molecules in the vacancies of the crystal lattice of neodymium fluoride. The strength (length) of the hydrogen bonds cleaved at various, not strictly determined temperatures depends on the geometry of the vacancies including water molecules.
