Reaction of lithium hexafluorogermanate with hydrogen fluoride solutions

Summary

  1. 1.

    A study was made of the isothermal solubility of lithium hexafluorogermanate in concentrated hydrogen fluoride solutions.

  2. 2.

    The solubility of Li2GeF6 in anhydrous hydrogen fluoride is 2.51%.

  3. 3.

    A decrease in the hydrogen fluoride concentration in the system Li2GeF6-HF-H2O leads to an irreversible transformation of the phases in the system with the deposition of lithium fluoride in the precipitate.

  4. 4.

    The deposition of LiF in the solid phase at HF concentrations ≤60% must be explained as being due to the sharp reduction in the solubility of lithium fluoride in aqueous HF solutions when compared with its solubility in 100% HF.
