HfC fine powders of single phase were successfully prepared by heating powder mixtures of Mg and HfO_2 with molar ratio of 4 and 5 at 800゜-950℃ for 1 h in a 25-100 vol% CH_4 flow. The formation process of HfC powders was as follows: (1)HfO_2+2Mg→α-Hf+_2MgO, (2)3CH_4+2Mg→Mg_2C_3+6H_2, (3)Mg_2C_3→2Mg+3C, (4)α-Hf+xC+y/2H_2→HfC_xH_y and (5)HfC_xH_y+(1-x)C→HfC+y/2H_2. Where, the above reactions took place above 650℃ in parallel. It was found that hydrogen and carbon for HfC_xH_y were supplied by the reaction of CH_4 with Mg and by thermal decomposition of Mg_2C_3, and carbon of HfC was also supplied by the thermal decomposition of Mg_2C_3. The supply of hydrogen and carbon continued according to a recycle of Mg (Mg→Mg_2C_3→Mg) which exists in the reaction system.","subitem_description_type":"Abstract"}]},"item_119_description_21":{"attribute_name":"注記","attribute_value_mlt":[{"subitem_description":"rights: 社団法人日本セラミックス協会\nrights: 本文データは学協会の許諾に基づきCiNiiから複製したものである\nrelation: IsVersionOf: http://ci.nii.ac.jp/naid/110002290316/","subitem_description_type":"Other"}]},"item_119_description_29":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"text","subitem_description_type":"Other"}]},"item_119_description_30":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_119_publisher_11":{"attribute_name":"出版者名","attribute_value_mlt":[{"subitem_publisher":"社団法人日本セラミックス協会"}]},"item_119_source_id_14":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"09145400","subitem_source_identifier_type":"ISSN"}]},"item_119_text_27":{"attribute_name":"版","attribute_value_mlt":[{"subitem_text_value":"[出版社版]"}]},"item_119_text_3":{"attribute_name":"著者 ローマ字","attribute_value_mlt":[{"subitem_text_value":"KOBAYASHI, Hidehiko"},{"subitem_text_value":"SHIMOSAKA, Kenichi"},{"subitem_text_value":"KAMIYAMA, Yoshihide"},{"subitem_text_value":"MITAMURA, Takashi"}]},"item_119_text_32":{"attribute_name":"アイテムID","attribute_value_mlt":[{"subitem_text_value":"A1002232"}]},"item_119_text_4":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"埼玉大学大学院理工学研究科物質科学部門"},{"subitem_text_value":"埼玉大学工学部応用化学科"},{"subitem_text_value":"徳山曹達(株)藤沢研究所"},{"subitem_text_value":"埼玉大学工学部"}]},"item_119_text_5":{"attribute_name":"著者 所属(別言語)","attribute_value_mlt":[{"subitem_text_value":"Departmelet of Applied Chemistry, Faculty of Engineering, Saitama University"},{"subitem_text_value":"Departmelet of Applied Chemistry, Faculty of Engineering, Saitama University"},{"subitem_text_value":"Fujisawa Research Laboratory, Tokuyama Soda Co., Ltd."},{"subitem_text_value":"Faculty of Engineering, Saitama University"}]},"item_119_text_9":{"attribute_name":"年月次","attribute_value_mlt":[{"subitem_text_value":"1993-3"}]},"item_119_version_type_28":{"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":"小林, 秀彦"},{"creatorName":"コバヤシ, ヒデヒコ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"下坂, 建一"},{"creatorName":"シモサカ, ケンイチ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"神山, 美英"},{"creatorName":"カミヤマ, ヨシヒデ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"三田村, 孝"},{"creatorName":"ミタムラ, タカシ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-01-24"}],"displaytype":"detail","filename":"A1002232.pdf","filesize":[{"value":"648.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"A1002232.pdf","url":"https://sucra.repo.nii.ac.jp/record/12982/files/A1002232.pdf"},"version_id":"fbe511a5-6525-448c-bb3e-7ea5c955e1ff"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Preparation","subitem_subject_scheme":"Other"},{"subitem_subject":"HfC","subitem_subject_scheme":"Other"},{"subitem_subject":"Thermite method","subitem_subject_scheme":"Other"},{"subitem_subject":"Mg","subitem_subject_scheme":"Other"},{"subitem_subject":"CH_4","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Mg還元テルミット法によるHfCの微粉末合成と生成過程","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Mg還元テルミット法によるHfCの微粉末合成と生成過程"}]},"item_type_id":"119","owner":"3","path":["426"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-01-09"},"publish_date":"2008-01-09","publish_status":"0","recid":"12982","relation_version_is_last":true,"title":["Mg還元テルミット法によるHfCの微粉末合成と生成過程"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-05-16T12:44:56.992650+00:00"}
