Topological Analysis of Phase Equilibria in the Hg – H

The analysis of the joint stability of phases and valence forms of mercury in the Hg – H2O system in the lg f O2 – 1/T coordinates for the temperature range from -50 to + 360°C was carried out by method of F. Schreinemakers. Analysis of equilibrium valence forms showed that for the composition of fluid phases, the non-autonomy of the oxide film as a phase on the surface of liquid mercury is key
