Hydride decomposition characterization by means of “morphological trajectory” method-Applied to AlH3

▶ Modeling of hydride decomposition kinetics for free-form shape of particles. ▶ Interrelations of kinetic parameters and morphology of growing phase. ▶ Rate of alane decomposition is limited by the reaction at interface. ▶ Rising of reaction temperature leads to the smaller quantity of Al-phase nuclei.
