Thermodynamics of thermolysis of alkali metals borohydrides

Abstract

Theoretical investigation of phase transformation of borohydrides of alkali metals has been performed on the basis of molecular-kinetic theory in the approach of the pair interaction of nearest atoms. The elaborated statistical theory of phase transformations at the realization of chemical reactions between phases of borohydrides of alkali metals gives the explanation and justification for the course of these reactions and provides the investigation of phase diagram with full details for the components of studied reactions. The knowledge of phase parameters for each concrete reaction from independent experiments predetermines the conditions of such reactions performance and the conditions of extraction of hydrogen as power source. The comparison of theoretical results with the experimental data for phase transformations of borohydrides of alkali metals shows the good agreement.
