The structural and hydrogen storage properties of them were investigated. We found new series of C14-type Laves phase compounds which absorb much hydrogen of 5～7 mass% at room temperature. Unfortunately, no samples prepared show the reversible property of hydrogen absorbing and desorbing. Using the arc melting, the induction melting and the mechanical milling methods, respectively, new composites of CaLi_2 and LaNi_5 were synthesized. It is expected that interesting hydriding properties are found out in the samples prepared by the mechanical milling method, because the XRD pattern of them show only peaks indexed by the reflection from LaNi_5. New perovskite-type hydrides were synthesized by milling the mixed powders of CaLi_2 and MgH_2, SrH_2 and BaH_2, respectively, in a hydrogen atmosphere of 3 MPa. Perovskite-type hydrides of SrLiH_3 and BaLiH_3 with high purity crystallization were prepared by this method.","subitem_description_type":"Abstract"}]},"item_8_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"平成20~22年度科学研究費補助金(基盤研究(C))研究成果報告書","subitem_description_type":"Other"}]},"item_8_description_64":{"attribute_name":"科研費番号","attribute_value_mlt":[{"subitem_description":"20560651","subitem_description_type":"Other"}]},"item_8_publisher_30":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"三重大学"}]},"item_8_text_18":{"attribute_name":"その他のタイトル","attribute_value_mlt":[{"subitem_text_value":"Structural and Hydrogen Storage Properties of Extremely Lightweight Compounds Synthesized from Laves Phase CaLi_2 Based System"}]},"item_8_text_65":{"attribute_name":"資源タイプ（三重大）","attribute_value_mlt":[{"subitem_text_value":"Kaken / 科研費報告書"}]},"item_8_version_type_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"牧原, 義一","creatorNameLang":"ja"},{"creatorName":"MAKIHARA, Yoshikazu","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-02-18"}],"displaytype":"detail","filename":"20K16705.pdf","filesize":[{"value":"491.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"20K16705.pdf","url":"https://mie-u.repo.nii.ac.jp/record/7403/files/20K16705.pdf"},"version_id":"86f077f4-2012-4895-92ff-b5e189ce0fe7"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"水素貯蔵合金","subitem_subject_scheme":"Other"},{"subitem_subject":"ラーベス相","subitem_subject_scheme":"Other"},{"subitem_subject":"CaLi2","subitem_subject_scheme":"Other"},{"subitem_subject":"複合化","subitem_subject_scheme":"Other"},{"subitem_subject":"ペロブスカイト型水素化物","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"超軽量カルシウム－リチウム系ラーベス相合金の水素化特性","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"超軽量カルシウム－リチウム系ラーベス相合金の水素化特性","subitem_title_language":"ja"}]},"item_type_id":"8","owner":"15","path":["1692661405337"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2014-03-10"},"publish_date":"2014-03-10","publish_status":"0","recid":"7403","relation_version_is_last":true,"title":["超軽量カルシウム－リチウム系ラーベス相合金の水素化特性"],"weko_creator_id":"15","weko_shared_id":-1},"updated":"2023-10-20T04:39:57.176808+00:00"}
