Hydrogen Sorption Properties of Potassium Alanate

Анотація

Molecular kinetic representations were used to develop the statistical theory of phase transformations of thermal decomposition of KAlH₄ potassium alanate with formation of a more complex K₃AlH₆ alanate and KH potassium hydride and subsequent dehydrogenation of the latter accompanied with free hydrogen, pure potassium and aluminum yield. Temperature dependence of the emitted free hydrogen was established. Isotherms and isopleths were built. The possibility of hysteresis effect manifestation was established. The results of calculations were compared to the experimental data.
