Abstract
(TG-DTA) thermal analyses of the Mg2NiH4 system revealed the presence of another hydride phase with composition Mg2NiH. The kinetic parameters for the phase transition as well as for the decomposition of the two hydride phases have been evaluated from DTA data using temperature programmed 'Arrhenius plots'. The thermodynamic quantities, namely the enthalphy and entropy changes for the two phases, have been evaluated and compared with the data reported in the literature. © 1988.
