采用反应球磨法使 Ｍｇ在 ＺｒＦｅ１．４Ｃｒ０．６的催化作用下直接氢化生成纳米结构的 ＭｇＨ２和ｒ－ＭｇＨ２利用 Ｘ射线衍射及热重分析对氢化相的生成进行分析和表征．在反应球磨过程中存在动态的氢化平衡．
Hydrogenation of Mg to the nanostructured MgH2 and r-MgH2 by direct ball milling under the catalysis of ZrFe1.4Cr0.6 was carried out. The formation of hydrogenated phase was analyzed and characterized by X-ray diffraction and thermogravimetric analysis. There is a dynamic hydrogenation equilibrium during the reaction milling.
