The thermal decomposition of a condensed H3BO3-polyol product in air was performed to control the amount of carbon to the stoichiometric C/B2O3 ratio required for carbothermal reduction. Within the thermally decomposed product consisting of B2O3 and carbon components (B4C precursor), a B2O3/carbon structure at the nanometer scale was formed. The improved dispersibility and homogeneity of the B2O3/carbon microstructure accelerated the B4C formation at a lower temperature. Consequently, crystalline B4C powder with little free carbon was synthesized by heat treatment at a low temperature of 1200 ℃ in an Ar flow. This low-temperature synthesis approach was applied to the low-temperature synthesis of other boride powders.","subitem_description_type":"Other"}]},"item_120_description_29":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"text","subitem_description_type":"Other"}]},"item_120_description_30":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_120_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24561/00018465","subitem_identifier_reg_type":"JaLC"}]},"item_120_publisher_11":{"attribute_name":"出版者名","attribute_value_mlt":[{"subitem_publisher":"埼玉大学研究機構科学分析支援センター"}]},"item_120_publisher_12":{"attribute_name":"出版者名（別言語）","attribute_value_mlt":[{"subitem_publisher":"Comprehensive Analysis Center for Science, Saitama University"}]},"item_120_text_27":{"attribute_name":"版","attribute_value_mlt":[{"subitem_text_value":"[出版社版] "}]},"item_120_text_3":{"attribute_name":"著者 ローマ字","attribute_value_mlt":[{"subitem_text_value":"KOBAYASHI, Hidehiko"},{"subitem_text_value":"KAKIAGE, Masaki"}]},"item_120_text_32":{"attribute_name":"アイテムID","attribute_value_mlt":[{"subitem_text_value":"KY-AA12504266-09-04"}]},"item_120_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":"信州大学先鋭領域融合研究群 国際ファイバー工学研究所"}]},"item_120_text_5":{"attribute_name":"著者 所属(別言語)","attribute_value_mlt":[{"subitem_text_value":"Graduate School of Science and Engineering, Saitama University"},{"subitem_text_value":"Institute for Fiber Engineering, Shinshu University (IFES), Interdisciplinary Cluster for Cutting Edge Research (ICCER) Shinshu University"}]},"item_120_text_9":{"attribute_name":"年月次","attribute_value_mlt":[{"subitem_text_value":"2018"}]},"item_120_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":"撹上, 将規"},{"creatorName":"カキアゲ, マサキ","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":"2019-02-01"}],"displaytype":"detail","filename":"KY-AA12504266-09-04.pdf","filesize":[{"value":"857.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KY-AA12504266-09-04.pdf","url":"https://sucra.repo.nii.ac.jp/record/18484/files/KY-AA12504266-09-04.pdf"},"version_id":"be61f386-8636-4bbd-b335-d2eb296e826c"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"有機化合物を用いた前駆体構造制御によるホウ化物粉末の低温合成《マイレビュー》","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"有機化合物を用いた前駆体構造制御によるホウ化物粉末の低温合成《マイレビュー》"}]},"item_type_id":"120","owner":"15","path":["924"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-02-01"},"publish_date":"2019-02-01","publish_status":"0","recid":"18484","relation_version_is_last":true,"title":["有機化合物を用いた前駆体構造制御によるホウ化物粉末の低温合成《マイレビュー》"],"weko_creator_id":"15","weko_shared_id":-1},"updated":"2023-05-15T18:21:49.080315+00:00"}
