Abstract：
Thermal decomposition behaviors of TiH₂ powder under a owing helium atmosphere and in a low vac- uum condition have been studied using an in situ EXAFS technique. By an EXAFS analysis containing the multiple scattering paths including H atoms, the changes of the hydrogen stoichiometric ratio and the phase transformation sequence are obtained. The results demonstrate that the initial decomposition temperature is dependent on experi- mental conditions, which occurs, respectively, at about 300 and 400℃ in a low vacuum condition and under a owing helium atmosphere. During the decomposition process of TiH₂ in a low vacuum condition, the sample experiences a phase change process:δ(TiH₂)→δ (TiH_x)→δ(TiH_x)+β(TiH_x)→δ(TiH_x)+β(TiH_x)+α(Ti)→β(TiH_x)+α(Ti)→α(Ti)+β(Ti). This study o ers a way to detect the structural information of hydrogen. A detailed discussion about the decomposition process of TiH₂ is given in this paper.
