In the system, two ternary compounds, ErFeO_3 and Er_3Fe_50_12, were deemed stable and had nonstoichiometric composition, whereas ErFe_20_4 was not found to be stable. The present result was different from that of previous studies at 1200 ℃, in which ErFe_20_4 was stable along with the above two ternary compounds. Lattice constants of ErFeO_3 and Er_3Fe_50_12, prepared in air by a quenching method, were determined and compared with previous values, and showed slight differences. The Gibbs energy changes of the reactions in the Fe-0 system, Fe + 1/2 O_2 = FeO, 3 FeO + 1/2 0_2 = Fe_30_4, and 2/3 Fe_30_4 + 1/6 0_2 = Fe_20_3, were determined, and the obtained values were compared with the previous values. The Gibbs energy changes of the reactions, Fe + 1/2 Er_20_3 + 3/4 0_2 = ErFe0_3, and 3 ErFeO_3 + 2/3 Fe_3O_4 + 1/6 0_2 = Er_3Fe_50_12, were calculated from the oxygen partial pressures in equilibrium.","subitem_description_type":"Abstract"}]},"item_2_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"新潟工科大学"}]},"item_2_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1342-792X","subitem_source_identifier_type":"ISSN"}]},"item_2_source_id_9":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN10590360","subitem_source_identifier_type":"NCID"}]},"item_2_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":"Kitayama, Kenzo"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ono, Makoto"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yamaguchi, Junpei"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ikarashi, Makoto"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Suzuki, Kousuke"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-02-25"}],"displaytype":"detail","filename":"10_1-9.pdf","filesize":[{"value":"749.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"10_1-9.pdf","url":"https://niit.repo.nii.ac.jp/record/128/files/10_1-9.pdf"},"version_id":"07d7b4f4-582f-4d96-811a-fe6a01edcb71"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Plase equilibrium"},{"subitem_subject":"Thermogravimetry"},{"subitem_subject":"Erbium-iron oxide"},{"subitem_subject":"Gibbs energy"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"Phase Equilibrium in the Er-Fe-O System at 1100℃","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Phase Equilibrium in the Er-Fe-O System at 1100℃","subitem_title_language":"en"}]},"item_type_id":"2","owner":"4","path":["17"],"pubdate":{"attribute_name":"公開日","attribute_value":"2010-11-08"},"publish_date":"2010-11-08","publish_status":"0","recid":"128","relation_version_is_last":true,"title":["Phase Equilibrium in the Er-Fe-O System at 1100℃"],"weko_creator_id":"4","weko_shared_id":-1},"updated":"2023-06-20T05:20:04.964239+00:00"}
