Also number of oxygen vacancies in the synthesized powders was estimated from the density, and conductivity of the resulting sintered bodies was measured. The number of oxygen vacancies in the Y_3NbO_7 powder in the x=0.25 composition synthesized in Ar was around 1.48 in unit cell even after heat treatment in air. The number of oxygen vacancies in the x=0.20 and 0.30 compositions synthesized in air increased by the change of valence number in Nb. On the other hand, after synthesizing the powder comprised of the x=0.20 composition in Ar, the number of oxygen vacancy of the powder reheated in air was 2.06. The conductivity of sintered bodies fabricated from the Y_3NbO_7 powders synthesized in Ar was raised by a half digit higher than that of the sintered body fabricated from the powders synthesized in air. The conductivity of the sintered bodies obtained from the synthesized powders increased almost linearly with an increase in the number of oxygen vacancies. Therefore, it was found that the introduction of oxygen vacancies by controlling composition and the powder preparation was an important factor for increasing in conductivity of Y_3NbO_7 sintered body.","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/110002290381/","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":"OGINO, Hiroyuki"},{"subitem_text_value":"MORI, Toshiyuki"},{"subitem_text_value":"YAMAMURA, Hiroshi"},{"subitem_text_value":"MITAMURA, Takashi"}]},"item_119_text_32":{"attribute_name":"アイテムID","attribute_value_mlt":[{"subitem_text_value":"A1002230"}]},"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":"東ソー(株)筑波研究所"},{"subitem_text_value":"東ソー(株)筑波研究所"},{"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":"Department of Applied Chemistry, Faculty of Engineering, Saitama University"},{"subitem_text_value":"Department of Applied Chemistry, Faculty of Engineering, Saitama University"},{"subitem_text_value":"Tsukuba Research Laboratory, TOSOH Co., Ltd."},{"subitem_text_value":"Tsukuba Research Laboratory, TOSOH 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":"1993-6"}]},"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":"荻野, 博幸"},{"creatorName":"オギノ, ヒロユキ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"森, 利之"},{"creatorName":"モリ, トシユキ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"山村, 博"},{"creatorName":"ヤマムラ, ヒロシ","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":"A1002230.pdf","filesize":[{"value":"520.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"A1002230.pdf","url":"https://sucra.repo.nii.ac.jp/record/12980/files/A1002230.pdf"},"version_id":"829ad9c5-f8f8-4c25-a2cc-f3629919c9d5"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"YCl_3","subitem_subject_scheme":"Other"},{"subitem_subject":"NbCl_5","subitem_subject_scheme":"Other"},{"subitem_subject":"Conductivity","subitem_subject_scheme":"Other"},{"subitem_subject":"Y_3NbO_7","subitem_subject_scheme":"Other"},{"subitem_subject":"Oxygen vacancy","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":"過剰な酸素イオン空孔を有するY_3NbO_7の粉末合成と導電性","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"過剰な酸素イオン空孔を有するY_3NbO_7の粉末合成と導電性"}]},"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":"12980","relation_version_is_last":true,"title":["過剰な酸素イオン空孔を有するY_3NbO_7の粉末合成と導電性"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-05-16T12:44:57.538758+00:00"}
