Аннотация

Stability regions of crystal phases in the water–hydrogen system have been studied within our statistical thermodynamic model for describing clathrate compounds. The thermodynamic stability of hydrogen-containing ices I _h (C ₀ ^Ih ), II (C ₁ ), I _c (C ₂ ), classical clathrate hydrogen hydrate CS-II, and new hydrogen-filled ice phase C ₀ has been analyzed. It has been shown that all considered phases are thermodynamically stable, but phase C ₀ is metastable with respect to the other phases. The chemical potentials of water molecules in phases C ₀ and C ₁ are close to each other. As a result, metastable phase C ₀ is experimentally observed in the stability region of phase C ₁ .
