Virgin alumina samples were fabricated by atmospheric sintering and were crushed into powder under 500 μm in grain size by thermal shock treatment and automatic mortar crushing. Then, the crushed alumina powder was mixed with virgin alumina powder and was subjected to re-sintering to renewed alumina. The renewed alumina samples were subjected to four-point bending test and SEM observation of microstructure. Relative density and bending strength of renewed alumina decreased as the volume fraction of recycled alumina powder increased. Samples over 200 MPa of average bending strength, however, were obtained by mixing 50 vol% recycled alumina powder with grain size<32 μm, which was much larger than that of virgin alumina powder. SEM observation indicated that pore distribution was inhomogeneous and pores were located along large polycrystal grain boundaries. Pores, consequently, formed cracks which markedly decreased bending strength. Furthermore, 10 vol%-glass containing renewed alumina samples were fabricated by a procedure similar to that of monolithic alumina. These samples showed higher bending strength than monolithic renewed alumina.","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/110002289764/","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_3":{"attribute_name":"著者 ローマ字","attribute_value_mlt":[{"subitem_text_value":"KAGEYAMA, Kensuke"},{"subitem_text_value":"KATO, Hiroshi"},{"subitem_text_value":"OHI, Kenzi"},{"subitem_text_value":"KOBAYASHI, Susumu"}]},"item_119_text_32":{"attribute_name":"アイテムID","attribute_value_mlt":[{"subitem_text_value":"A1002218"}]},"item_119_text_4":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"埼玉大学工学部機械工学科"},{"subitem_text_value":"埼玉大学工学部機械工学科"},{"subitem_text_value":"埼玉大学工学部機械工学科"},{"subitem_text_value":"埼玉大学工学部機械工学科"}]},"item_119_text_5":{"attribute_name":"著者 所属(別言語)","attribute_value_mlt":[{"subitem_text_value":"Department of Mechanical Engineering, Faculty of Engineering, Saitama University"},{"subitem_text_value":"Department of Mechanical Engineering, Faculty of Engineering, Saitama University"},{"subitem_text_value":"Department of Mechanical Engineering, Faculty of Engineering, Saitama University"},{"subitem_text_value":"Department of Mechanical Engineering, Faculty of Engineering, Saitama University"}]},"item_119_text_9":{"attribute_name":"年月次","attribute_value_mlt":[{"subitem_text_value":"1999-5"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"蔭山, 健介"},{"creatorName":"カゲヤマ, ケンスケ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"加藤, 寛"},{"creatorName":"カトウ, ヒロシ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"大井, 健司"},{"creatorName":"オオイ, ケンジ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"小林, 進"},{"creatorName":"コバヤシ, ススム","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":"A1002218.pdf","filesize":[{"value":"2.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"A1002218.pdf","url":"https://sucra.repo.nii.ac.jp/record/12834/files/A1002218.pdf"},"version_id":"3a002563-7978-471d-9023-3aa2dba385fb"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Ceramics","subitem_subject_scheme":"Other"},{"subitem_subject":"Alumina","subitem_subject_scheme":"Other"},{"subitem_subject":"Recycle","subitem_subject_scheme":"Other"},{"subitem_subject":"Strength","subitem_subject_scheme":"Other"},{"subitem_subject":"Fracture","subitem_subject_scheme":"Other"},{"subitem_subject":"Glass","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":"再生原料を用いた焼結アルミナの力学的特性の評価","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"再生原料を用いた焼結アルミナの力学的特性の評価"}]},"item_type_id":"119","owner":"3","path":["426"],"pubdate":{"attribute_name":"公開日","attribute_value":"2007-09-21"},"publish_date":"2007-09-21","publish_status":"0","recid":"12834","relation_version_is_last":true,"title":["再生原料を用いた焼結アルミナの力学的特性の評価"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-05-16T12:49:02.466307+00:00"}
