摘要： 钛是其有吸氢作用的金属元素之一,用于制备超纯氢气[1,2].但纯金属钛作为储氢材料却一直认为没有实用价值[2].近年来对钛与氢作用引起的微观缺陷及钛的氢化物结构和形成机制等方面进行了一些研究[4,5].但并未娜决性与里作用的实用性问题.

关键词: 氢化钛, 制备, 分解

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
