X-ray diffraction studies revealed that the crystallization of so-called \"123 phase\" of YBa₂ Cu₃O₇_₈(YBCO) superconductors begins at 600~650℃ and grows up to the maximum level at 750℃ under this mixed argon gas flow, and that this growing range of the crystallization is about 100℃ lower than that for using air flow. BaCu0₂ and CuO, which are produced after thermal decomposition of nitrates, seem to behave in strong correlation with 123 phase in the whole process of sintering. At a temperature higher than 750°C, a greenish insulating region appeared in a boundary layer of samples contacting with a combustion boat. This crystal was assigned to \"211 phase\" of YBCO, which degrades the 123-crystality of the main part of the sample and also deteriorates its superconducting prop­erties.","subitem_description_type":"Other"}]},"item_3_full_name_2":{"attribute_name":"著者(ヨミ)","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"3245","nameIdentifierScheme":"WEKO"}],"names":[{"name":"ノダ, ミノル"}]}]},"item_3_full_name_3":{"attribute_name":"別言語の著者","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"3246","nameIdentifierScheme":"WEKO"}],"names":[{"name":"NODA, Minoru"}]}]},"item_3_publisher_37":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"福岡工業大学"}]},"item_3_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"02876620","subitem_source_identifier_type":"ISSN"}]},"item_3_text_38":{"attribute_name":"出版者(ヨミ)","attribute_value_mlt":[{"subitem_text_value":"フクオカ コウギョウ ダイガク"}]},"item_3_text_39":{"attribute_name":"別言語の出版者","attribute_value_mlt":[{"subitem_text_value":"Fukuoka Institute of Technology"}]},"item_3_text_48":{"attribute_name":"資源タイプ・ローカル","attribute_value_mlt":[{"subitem_text_value":"紀要論文"}]},"item_3_text_49":{"attribute_name":"資源タイプ・NII","attribute_value_mlt":[{"subitem_text_value":"Departmental Bulletin Paper"}]},"item_3_text_50":{"attribute_name":"資源タイプ・DCMI","attribute_value_mlt":[{"subitem_text_value":"text"}]},"item_3_text_51":{"attribute_name":"資源タイプ・ローカル表示コード","attribute_value_mlt":[{"subitem_text_value":"02"}]},"item_3_version_type_19":{"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":"野田, 稔"}],"nameIdentifiers":[{"nameIdentifier":"3244","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","displaytype":"detail","filename":"31(2)-361.pdf","filesize":[{"value":"757.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"url":"https://fit.repo.nii.ac.jp/record/694/files/31(2)-361.pdf"},"version_id":"37b160a0-ef4e-4d47-8c2a-0b1073b2a238"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"YBCO-nitrates","subitem_subject_scheme":"Other"},{"subitem_subject":"flowing gas containing 1% oxygen","subitem_subject_scheme":"Other"},{"subitem_subject":"crystalization","subitem_subject_scheme":"Other"},{"subitem_subject":"sintering in the lower temperature","subitem_subject_scheme":"Other"},{"subitem_subject":"123 phase","subitem_subject_scheme":"Other"},{"subitem_subject":"211 phase","subitem_subject_scheme":"Other"},{"subitem_subject":"BaCuO₂","subitem_subject_scheme":"Other"},{"subitem_subject":"CuO","subitem_subject_scheme":"Other"},{"subitem_subject":"YBCO-nitrates","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"flowing gas containing 1% oxygen","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"crystalization","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"sintering in the lower temperature","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"123 phase","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"211 phase","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"BaCuO₂","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"CuO","subitem_subject_language":"en","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"低酸索濃度気流中におけるY, Ba, Cu硝酸塩混合粉末の焼成","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"低酸索濃度気流中におけるY, Ba, Cu硝酸塩混合粉末の焼成"},{"subitem_title":"Sintering of Mixed Powder of Y -, Ba- and Cu-Nitrates in Flowing Gas Containing Small Amount of Oxygen","subitem_title_language":"en"}]},"item_type_id":"3","owner":"6","path":["366"],"pubdate":{"attribute_name":"公開日","attribute_value":"2021-02-25"},"publish_date":"2021-02-25","publish_status":"0","recid":"694","relation_version_is_last":true,"title":["低酸索濃度気流中におけるY, Ba, Cu硝酸塩混合粉末の焼成"],"weko_creator_id":"6","weko_shared_id":-1},"updated":"2023-05-15T13:59:44.220180+00:00"}
