La thermodynamique des hydrates cristallins : stoechiométrie. // The thermodynamic of solid hydrates: stoichiometry.
Résumé
The thermodynamic properties of the divariant equilibra between solid hydrates and water vapour are studied with three models : Polanyi's model, the solid solutions model and the structure elements model. The third model generalizes the first and the second. Relations between the equations of isotherms and some properties of water molecules in the solid (mobility, interactions, associations) are established. The problem of the limits of divariant spaces is studied by the third model treatment.
