Prospects of Producing Hydrogen-Ammonia Fuel Based on Lithium Aluminum Amide

The paper presents the development of the statistical theory of phase transformation of lithium aluminum amide with the formation of ammonia. Free energies of phases are calculated, and their dependences on temperature, pressure, hydrogen concentration and energy parameters are suggested. The phase diagram is suggested and thermodynamic equilibrium is calculated herein. Isothermal processes in phases are investigated. Rectangularity and structure degree coefficients are calculated for isotherms. The temperature dependence is identified for the hydrogen concentration in phases.
