Thermal characterization of titanium hydride in thermal oxidation process

We investigated the thermal behavior of titanium hydride with different particle size at the different atmospheres using the thermal analysis techniques. The results demonstrated that the smaller particle has larger reactivity and showed less stable at higher heating rates. Even in the thermal plasma with inert atmosphere, titanium hydride was partially oxidized and an effective oxidation occurs in thermal plasma reactor with oxygen as reactive gas. Milling process changed the stoichiometry of titanium hydride from TiH2 to TiHy and the amount of hydrogen in titanium hydride affects its oxidation behavior.

► Thermal characterization of titanium hydride in thermal oxidation process. ► Initially oxidation was carried out in TG-DTA in static air environment. ► Effect of milling has been analyzed on the reactivity of oxidation in TG-DTA analysis, leads to partial oxidation. ► Oxidation process was carried out in thermal plasma environment with oxygen as reactive gas effectively. ► Thermal Plasma oxidation occurs effectively from titanium hydride to titanium dioxide with anatase and rutile phases.
