Thermal Analysis of Mg₂Cu Hydride

The desorption kinetics of $Mg_2Cu$ hydride were studied by thermal analysis technique in order to study desorption behavior and to relate thermal desorpton spectra to occuption site of hydrogen. It is suggested that a continuous ${\alpha}/{\beta}$ interface boundary is formed at the initial absorption stage. And the desorption kinetics were analysed by the theoretical equation which was derived on the basis of continous moving boundary model. The number of thermal desorption peak corresponds to the occupation sites of hydrogen. The apparent activation energy for the desorption of $Mg_2Cu$ hydride is 91 KJ/mol.
