It was confirmed that all Al-free LLZTa have the cubic garnet related structure, while Al-free LLZ without Ta substitution has tetragonal one. No other secondary phases were observed in all sintered samples. This indicates that partial substitution of Zr4+ by Ta5+ with higher valence increases Li-ion vacancy concentration in a garnet framework and stabilizes cubic garnet structure. The LLZTa grains are in good contact with each other although a certain amount of pores in the boundary area can be observed. Total (bulk + grain boundary) Li-ion conductivity at 27°C for all Al-free LLZTa were well above 10-4 Scm-1, while Al-free LLZ showed much lower room temperature conductivity of 1 × 10-5 Scm-1. The highest room temperature conductivity of 6.1 × 10-4 Scm-1 was obtained in Al-free LLZTa with x = 0.5, which is approximately 30−40% lower than the value in LLZTa (x = 0.5) with Al inclusion as previously reported.","subitem_description_type":"Abstract"}]},"item_10003_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Elsevier"}]},"item_10003_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1016/j.ssi.2013.09.008","subitem_relation_type_select":"DOI"}}]},"item_10003_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"ScienceDirect"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.sciencedirect.com/science/article/pii/S0167273813004074","subitem_relation_type_select":"URI"}}]},"item_10003_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":" © 2014, Elsevier"}]},"item_10003_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"稲田, 亮史"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"日下部, 晃司"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"田中, 貴之"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"工藤, 翔太"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"櫻井, 庸司"}],"nameIdentifiers":[{},{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2014-06-25"}],"displaytype":"detail","filename":"SSI-19 Inada manuscript fin-1.pdf","filesize":[{"value":"1.5 MB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"ssi2014-0568","url":"https://repo.lib.tut.ac.jp/record/1351/files/SSI-19 Inada manuscript fin-1.pdf"},"version_id":"6c163538-bcc3-43b3-a839-d1e481e75bcb"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Li7La3Zr2O12 garnet","subitem_subject_scheme":"Other"},{"subitem_subject":"cubic structure","subitem_subject_scheme":"Other"},{"subitem_subject":"Al-free","subitem_subject_scheme":"Other"},{"subitem_subject":"Ta substitution","subitem_subject_scheme":"Other"},{"subitem_subject":"ionic conductivity","subitem_subject_scheme":"Other"}]},"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":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"Synthesis and properties of Al-free Li7-xLa3Zr2-xTaxO12 garnet related oxides","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Synthesis and properties of Al-free Li7-xLa3Zr2-xTaxO12 garnet related oxides"}]},"item_type_id":"10003","owner":"27","path":["10"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-06-25"},"publish_date":"2014-06-25","publish_status":"0","recid":"1351","relation_version_is_last":true,"title":["Synthesis and properties of Al-free Li7-xLa3Zr2-xTaxO12 garnet related oxides"],"weko_creator_id":"27","weko_shared_id":-1},"updated":"2023-06-19T07:52:43.056799+00:00"}
