Isothermal decomposition of LiAlD4

A model based on the John-Mehl Avrami formalism has been successfully applied to predict the amount of deuterium released during isothermal decomposition of LiAlD4, as-received or mechanically milled with Al or VCl3. The John-Mehl Avrami parameters indicate that for LiAlD4 not mixed with additives the nucleation of the new phases during its decomposition is of the continuous nucleation type while for LiAlD4 ball-milled with VCl3, the nucleation is of the site saturation type.
