About 4.5 mass% hydrogen is desorbed from about 100 °C and the thermal desorption profiles show a peak around 200 and 220 °C for the composites of CaH2+2LiNH2 and Ca(NH2)2+2LiH, respectively, under a helium flow at 5 °C/min heating rate without any NH3 emission within our experimental accuracy. The powder X-ray diffraction and infrared absorption spectroscopy indicated that the dehydrogenated states of both composites form \"an unknown imide phase\" after heating up to 400 °C, while the dehydrogenated states after heating up to 200 °C in vacuum are the mixed phases of Li2NH and CaNH. The rehydrogenated state for the ball-milled composite of CaH2+2LiNH2 is transformed into the composite of Ca(NH2)2 and 2LiH by repeating the dehydrogenation and rehydrogenation cycles at 180~200 °C.","subitem_description_language":"en"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_publisher":"Elsevier B.V."}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_source_identifier":"0925-8388","subitem_source_identifier_type":"ISSN"},{"subitem_source_identifier":"AA10817249","subitem_source_identifier_type":"NCID"}]},"item_1617187024783":{"attribute_name":"Page Start","attribute_value_mlt":[{"subitem_start_page":"337"}]},"item_1617187056579":{"attribute_name":"Bibliographic Information","attribute_value_mlt":[{"bibliographicIssueDates":{"bibliographicIssueDate":"2007-07-31","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"1-2","bibliographicPageEnd":"341","bibliographicPageStart":"337","bibliographicVolumeNumber":"439","bibliographic_titles":[{"bibliographic_title":"Journal of Alloys and Compounds"},{"bibliographic_title":"Journal of Alloys and Compounds"}]}]},"item_1617258105262":{"attribute_name":"Resource Type","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_1617265215918":{"attribute_name":"Version Type","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_b1a7d7d4d402bcce","subitem_version_type":"AO"}]},"item_1617353299429":{"attribute_name":"Relation","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1016/j.jallcom.2006.08.234","subitem_relation_type_select":"DOI"}},{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://dx.doi.org/10.1016/j.jallcom.2006.08.234","subitem_relation_type_select":"DOI"}}]},"item_1617605131499":{"attribute_name":"File","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2023-03-18"}],"displaytype":"simple","filename":"JAllCompd_439_1-2_337.pdf","filesize":[{"value":"434.5 KB"}],"mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://hiroshima.repo.nii.ac.jp/record/2007177/files/JAllCompd_439_1-2_337.pdf"},"version_id":"1723ce49-60d5-4707-b483-cdfe6a68ef2b"}]},"item_1732771732025":{"attribute_name":"旧ID","attribute_value":"20036"},"item_title":"Hydrogen desorption/absorption properties of Li-Ca-N-H system","item_type_id":"40003","owner":"41","path":["1730444907710"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-03-18"},"publish_date":"2023-03-18","publish_status":"0","recid":"2007177","relation_version_is_last":true,"title":["Hydrogen desorption/absorption properties of Li-Ca-N-H system"],"weko_creator_id":"41","weko_shared_id":-1},"updated":"2025-02-21T09:24:21.643419+00:00"}
