The cation and oxide ion deficient perovskite-type oxides LnA2-xTi2AlO9-d(Ln=La, Nd;A=Ca, Sr) were synthesized. Single-phase samples of LnA2-xTi2AlO9-d were prepared by heating at 1673 K in air in the compositional range of x=0-0.3 for both A = Ca and Sr. The crystal structures were cubic perovskite-type for A = Sr and orthorhombic perovskite-type for A=Ca. Lattice parameters of LnA2-xTi2AlO9-d increased with increasing amounts of A cation vacancies. All the samples exhibited semiconducting behavior in the temperature range of 573-1023 K in air. The measurements of conductivity for LnA2-xTi2AlO9-d as a function of oxygen partial pressure revealed n-type conductivity at oxygen partial pressure less than 0.21 arm. The conductivities of LnA2-xTi2AlO9-d increased with increasing amount of A cation and oxide ion vacancies for both A=Ca and Sr.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"The Society of Materilas Engineering for resources of Japan","subitem_publisher_language":"en"}]},"item_10001_relation_25":{"attribute_name":"関連情報","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.5188/ijsmer.10.61","subitem_relation_type_select":"DOI"}}]},"item_10001_version_type_20":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_1724099666130":{"attribute_name":"収録物識別子","attribute_value_mlt":[{"subitem_source_identifier":"13479725","subitem_source_identifier_type":"ISSN"},{"subitem_source_identifier":"AA1095475X","subitem_source_identifier_type":"NCID"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"作成者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Kato, Sumio","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"MatsukiI, Yukio","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Maruyama, Takahiro","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Moriya, Yoshio","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Sugai, Mikio","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Nakata, Shinichi","creatorNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-02-16"}],"displaytype":"detail","filename":"ijsmer10-1i.pdf","filesize":[{"value":"565.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ijsmer10-1i.pdf","url":"https://air.repo.nii.ac.jp/record/950/files/ijsmer10-1i.pdf"},"version_id":"74f653ea-42d6-41f5-b713-6119505fe795"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"perovskite","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"crystal structure","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"cation vacancy","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"oxide ion conductor","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"electrical conductivity","subitem_subject_language":"en","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Synthesis and Electrical Properties of Cation Deficient Perovskite-type Oxides in the Ln-A-Ti-AI-0 System (Ln = La, Nd;A=Ca, Sr).","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Synthesis and Electrical Properties of Cation Deficient Perovskite-type Oxides in the Ln-A-Ti-AI-0 System (Ln = La, Nd;A=Ca, Sr).","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"15","path":["682"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2008-03-28"},"publish_date":"2008-03-28","publish_status":"0","recid":"950","relation_version_is_last":true,"title":["Synthesis and Electrical Properties of Cation Deficient Perovskite-type Oxides in the Ln-A-Ti-AI-0 System (Ln = La, Nd;A=Ca, Sr)."],"weko_creator_id":"15","weko_shared_id":-1},"updated":"2024-08-25T10:41:47.583276+00:00"}
