Abstract: The thermal decomposition kinetics of α-AIH_3 in helium flow was investigated by differential thermal analysis(DTA).
The thermal decomposition curve for of α-AIH_3 is an endothermal process, it yields sigmoidal fraction of decomposition(x)vs.time, the main part of which can be expressed by Avrami-Erofeev (A-E) equation[-In (1-x)]1/n=r_0e~(R/RT). The correlation formula between DTA curve and kinetic parameters in A-E equation was derived under conditions of linear temperature increase.
