Аннотация: The heat capacity of partially deuterated crystals with a cryolite structure, namely, (NH4)(3)ScF6 and (NH4)(3)GaF6, is measured in the temperature range from 80 to 370 K. The p-T phase diagrams of these compounds are investigated at pressures up to p = 0.6 GPa. It is revealed that the deuteration does not affect the sequences of phase transitions observed in the proton-containing ammonium cryolites studied earlier. The isotope effect most clearly manifests itself in significant changes in the thermodynamic parameters of the I12/m1-P (1) over bar low-temperature transformation in scandium cryolite.
