Abstract

Abstract: The titanium hydride was prepared in quartz tube reactor.Its formation and de-composition were examined by SEM, XRD and DTA.The results show that in about 350C, hydrogen and titanium can be fast combined into titanium hydride which mainly in irreg-ular polyhedron particles of 1~40 μm size, and in 680℃ the titanium hydride can be decom-posed producing hydrogen.The relationship between the partial pressure of hydrogen andtemperature was researched through thermodynamic discussion.

Key words: titanium hydride, formation, decomposition
