Two plateaus related to the reactions Mg2Ni+2H_2(?)Mg_2NiH_4 and Mg+H_2(?)MgH_2 respectively exhibit in the pressurecomposition isotherm of La_2Mg_(16)Ni alloy. Partial substitution of Mg by Ni in La_2Mg_(17) gives a two-phase mixture: the major is La_2Mg_(17) type phase and the minor, Mg_2Ni type one. Hydriding of the La_2Mg_(16)Ni alloy leads to the formation of MgH_2, La hydride and Mg_2NiH_4. An experiment was also carried out on the hydrogen absorption by the alloys under either normal temperature and lower pressure or normal pressure and elevated temperature. It was found that La_2Mg_(17) and La_2Mg_(16)Ni seem to be the considerable hydrogen storage materials. 收稿日期: 1983-04-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 申泮文 汪根时 张激志 杨喜增 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1983/V19/I4/108 1 张激志;汪根时,未发表资料,1982． 2 Reilly, J.
