Titanium is known to have a large affinity for hydrogen. Hydrogenation leads to the formation of titanium hydrides which present different stoichiometries such as TiH2, TiH, TiH1.5 [1]. TiH2 is mainly used in pyrotechnic and metallurgical areas, hydrogen storage media [1] and for preparation of the hydrogenated titanium alloys and ceramics based composites with biomedical applications [2]. Therefore, the TiH2 dehydrogenation process is important to be studied from the kinetic point of view, in order to understand the processes undergoing and to further develop the above mentioned applications; however, until now the TiH2 dehydrogenation kinetics is not clear and needs supplementary investigation. The non-isothermal dehydrogenation of TiH2 powder was studied using thermogravimetry (TG) and differential scanning calorimetry (DSC) in the temperature range 25 – 900 ºC, at the heating rates of 5, 7, 10, 12 and 15 K/min. Commercial TiH2 (100-150 μm; water atomised; >98 %; Merck) was used in this work. TiH2 was structurally and morphologically characterized by X-ray diffraction and scanning electron microscopy (SEM). The TiH2 mass rapidly decreases between 474 °C and 670 °C due to the release of hydrogen, with a maximum rate of decomposition at 579 °C corresponding to a sharp peak on the DTG curve (at 10 K/min). Above 670 °C (when the remaining mass was about 98.6% of gross mass), the TG curve indicates the gain in mass due to the slight oxidation of Ti in the presence of the oxygen incorporated in Ti network. The results showed that upon heating TiH2 undergoes a series of transformations in a three-step process. The activation parameters corresponding to these transformations are reported; also, the TiH2 dehydrogenation “activation” thermodynamic parameters were calculated.
