Abstract

Titanium hydride (TiH2) is of significant interest for titanium powder metallurgy and hydrogen storage material. TiH2 can be produced from titanium tetrachloride (TiCl4) reduced with calcium hydride (CaH2). In this study, the effects of temperature, time and amount of Ni as catalyst on the reduction process were evaluated. Temperature was between 300 and 500 ℃, reaction time was set between 3 and 5 h, and weight percentage of Ni to the CaH2 was from 10 to 50%. The weight of final powders was measured by element hydrogen analysis after each experiment. The highest weight gain (89.11%) was obtained for the sample reduced at 500 ℃ with 50% Ni catalyst for 3 h. Samples with higher weight gain were characterized by X-ray diffraction (XRD) and scanning electron microscope (SEM). The results indicate that producing of TiH2 from reduction of TiCl4 with CaH2 in the presence of Ni was feasible and could lead to low-temperature synthesis of TiH2.
