Preparation of titanium by hydrogenation and analysis of its energy
Titanium hydride was prepared from sponge titanium at different temperatures and time.Per-form structural analysis using X-ray diffraction(XRD)and morphology analysis using scanning electron microscopy(SEM).The results show that with the increase of reaction temperature,the mass growth rate of titanium hydride increases,and the brittleness also increases.When the temperature exceeds 500℃,there is little change in the mass growth rate.The thermodynamic calculation results show that when the temperature increases from 300℃to 700℃,the equilibrium constant significantly decreases,indicat-ing that a high reaction temperature is not conducive to the reaction.The calculation of adsorption en-ergy in the hydrogenation process shows that the optimal adsorption site is located at its central point.Solid solution energy analysis shows that hydrogen atoms tend to occupy octahedral gaps more.
