To adjust the .TAU.f value to zero, rutile (TiO2) with the high .TAU.f (450ppm/.DEG.C.) was added. When sintering temperature was selected as low as possible, TiO2 remained in the forsterite specimen, which raised .TAU.f from a negative to positive values. For instance, the 30wt% TiO2 added forsterite ceramics sintered at 1200.DEG.C. yield a high density (3.3g/cm3), which same as that of the same forsterite ceramics sintered at 1350.DEG.C.. A part of added TiO2 works for sintering aid and residual ones do for lowering the .TAU.f value. Forsterite ceramics have .TAU.f=0ppm/.DEG.C., .EPSILON.r=11 and Q f=82000GHz, when they contains 24wt% of TiO2 and sintered at 1200/.DEG.C. for 2h.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_10001_full_name_27":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"17524","nameIdentifierScheme":"WEKO"}],"names":[{"name":"角岡, 勉"}]},{"nameIdentifiers":[{"nameIdentifier":"8759","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"1000040335089","nameIdentifierScheme":"NRID","nameIdentifierURI":"http://rns.nii.ac.jp/nr/1000040335089"}],"names":[{"name":"柿本, 健一"}]},{"nameIdentifiers":[{"nameIdentifier":"17526","nameIdentifierScheme":"WEKO"}],"names":[{"name":"大里, 齊"}]}]},"item_10001_publisher_29":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"The Ceramic Society of Japan","subitem_publisher_language":"en"}]},"item_10001_source_id_30":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0914-5400","subitem_source_identifier_type":"ISSN"}]},"item_10001_source_id_32":{"attribute_name":"item_10001_source_id_32","attribute_value_mlt":[{"subitem_source_identifier":"AN10040326","subitem_source_identifier_type":"NCID"}]},"item_10001_version_type_33":{"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_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Tsunooka, Tsutomu","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"17519","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sugiyama, H","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"17520","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kakimoto, Ken-ichi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"8759","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"1000040335089","nameIdentifierScheme":"NRID","nameIdentifierURI":"http://rns.nii.ac.jp/nr/1000040335089"}]},{"creatorNames":[{"creatorName":"Osato, Hitoshi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"17522","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ogawa, H","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"17523","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-01-25"}],"displaytype":"detail","filename":"JCSJ 112_S1637.pdf","filesize":[{"value":"369.8 kB"}],"format":"application/pdf","license_note":"(c) 2004 The Ceramic Society of Japan","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"本文_fulltext","url":"https://nitech.repo.nii.ac.jp/record/5185/files/JCSJ 112_S1637.pdf"},"version_id":"a568a017-43c9-4ba7-b4b1-05dfdd65a66d"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"item_resource_type","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Zero Temperature Coefficient .TAU.f and Sinterability of Forsterite Ceramics by Rutile Addition","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Zero Temperature Coefficient .TAU.f and Sinterability of Forsterite Ceramics by Rutile Addition","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"91","path":["31"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2012-11-06"},"publish_date":"2012-11-06","publish_status":"0","recid":"5185","relation_version_is_last":true,"title":["Zero Temperature Coefficient .TAU.f and Sinterability of Forsterite Ceramics by Rutile Addition"],"weko_creator_id":"91","weko_shared_id":-1},"updated":"2025-03-19T05:10:24.014776+00:00"}
