Abstract
The decomposition curves of the solid solutions based on ices Ih (α-solutions) and II (β-solutions) in the water-hydrogen system were studied by the DTA technique at pressures up to 7 kbar. The α-solution is destabilized by pressure but to a lesser degree than ice Ih and is stable up to 2.3 kbar. Theβ-solution is stabilized by pressure and at 7 kbar decomposes at about 20°C. TheP, T-phase diagram of the water-hydrogen system in the crystallization range is constructed on the basis of reference [1] and our data. All possible types of stoichiometric interrelationships in the guest —host system are demonstrated by the example of the water-hydrogen system.
