Phase behavior and thermal properties of the system NH 4 F—HF 1
Journal Article

· Journal of Physical Chemistry
The system NH4F --HF was studied by thermal analysis between the limits NH4HF2and HF. No indication of the composition NH4H4F4 was found. Low temperature heat capacity measurements on four compositions approximating NH4H4F4 confirmed and extended the thermal analysis and revealed the existence of a solid solution at this composition. Several thermal anomalies were found between 180 °K and the melting point. The decomposition pressure of NH4H3F4 was also determined.
