The former was prepared by melting and contained 0.004～0.177 wt% water and the latter, by hydrolyzing metal alkoxide solutions. It is found that with increasing water content in the glass, the glass transition temperature and the rate of nucleation decrease, whereas the rate of crystal growth increases. It is also found that gels prepared from a metal alkoxide solution show a crystallization process different from glasses prepared by conventional melting method ; the crystalline phase precipitated from the former is metastable lithium metasilicate Li2SiO3 and that precipitated from the latter is stable lithium disilicate Li2Si2O3. It is also to be noted that the glass prepared by melting the gel shows a crystallization process similar to the glasses prepared by melting crystalline powders when their water contents are similar.","subitem_description_type":"Abstract"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"窯業協会"}]},"item_10001_relation_42":{"attribute_name":"関係URI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"http://ci.nii.ac.jp/naid/110002312665"}]}]},"item_10001_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"社団法人日本セラミックス協会"},{"subitem_rights":"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"}]},"item_10001_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00245650","subitem_source_identifier_type":"NCID"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0009-0255","subitem_source_identifier_type":"PISSN"}]},"item_10001_text_25":{"attribute_name":"その他のタイトル","attribute_value_mlt":[{"subitem_text_value":"Effect of water on the crystallization of Li2O-SiO2 glasses and gels"}]},"item_10001_text_70":{"attribute_name":"資源タイプ（三重大）","attribute_value_mlt":[{"subitem_text_value":"Journal Article / 学術雑誌論文"}]},"item_10001_version_type_20":{"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":"黄, 占杰","creatorNameLang":"ja"},{"creatorName":"Huang, Zhan Jie","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"横尾, 俊信","creatorNameLang":"ja"},{"creatorName":"Yoko, Toshinobu","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"神谷, 寛一","creatorNameLang":"ja"},{"creatorName":"Kamiya, Kanichi","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"作花, 済夫","creatorNameLang":"ja"},{"creatorName":"Sakka, Sumio","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":"2017-02-18"}],"displaytype":"detail","filename":"40A11432.pdf","filesize":[{"value":"703.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"40A11432.pdf","url":"https://mie-u.repo.nii.ac.jp/record/8330/files/40A11432.pdf"},"version_id":"c47acfe0-a307-48f7-bd8c-ba343246eb58"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Crystallization","subitem_subject_scheme":"Other"},{"subitem_subject":"Water","subitem_subject_scheme":"Other"},{"subitem_subject":"Lithium silicate","subitem_subject_scheme":"Other"},{"subitem_subject":"Glass","subitem_subject_scheme":"Other"},{"subitem_subject":"Gel","subitem_subject_scheme":"Other"},{"subitem_subject":"Nucleation","subitem_subject_scheme":"Other"},{"subitem_subject":"Crystal growth","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":"Li2O-SiO2系ガラス及びゲルの結晶化に対する水分の影響","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Li2O-SiO2系ガラス及びゲルの結晶化に対する水分の影響","subitem_title_language":"ja"}]},"item_type_id":"10001","owner":"15","path":["639"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2010-03-02"},"publish_date":"2010-03-02","publish_status":"0","recid":"8330","relation_version_is_last":true,"title":["Li2O-SiO2系ガラス及びゲルの結晶化に対する水分の影響"],"weko_creator_id":"15","weko_shared_id":-1},"updated":"2023-10-13T06:25:39.305184+00:00"}
