The developed statistical theory of thermal phase transformations in magnesium alanate, which are realized with increasing temperature, made it possible to explain and justify the phenomenon of dehydrogenation of the thermal decomposition products for magnesium alanate. The free energies of the phases have been calculated, and their dependence on temperature, pressure, hydrogen concentration, and energy parameters has been established. Thermodynamic equilibrium equations are obtained, from which the hydrogen concentrations in the phases are determined.
