The obtained SVG-CaO-MgO glass crystallized above 900°C. The crystal phases precipitated in the heat-treated SVG-CaO-MgO glass at 1100°C for 1 h were akermanite, diopside and forsterite.\nPhysical, optical, chemical and thermal properties and bending strength of the glasses were investigated. Results are as follows : apparent density 2.67~2.76g/cm^<3>, bending strength 539~882kg/cm^<2>, hardness (D.P.H) 613~713kg/mm^<2>, refractive index 1.578~1.622 ± 0.003, thermal expansion co-efficient (room temperature~700°C) 5.9~9.3×10^<-6>/°C. The glasses showed high resistance to alkaline solution, namely the mean weight loss of the glasses which had been treated by 2N-NaOH solution at 100°C for 14 h was so small as to be 0.7%.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_7_publisher_23":{"attribute_name":"公開者・出版者","attribute_value_mlt":[{"subitem_publisher":"鹿児島大学","subitem_publisher_language":"ja"},{"subitem_publisher":"Kagoshima University","subitem_publisher_language":"en"}]},"item_7_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0451212X","subitem_source_identifier_type":"PISSN"}]},"item_7_source_id_9":{"attribute_name":"NII書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00040363","subitem_source_identifier_type":"NCID"}]},"item_7_subject_15":{"attribute_name":"NDC","attribute_value_mlt":[{"subitem_subject":"501","subitem_subject_scheme":"NDC"}]},"item_7_version_type_14":{"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":"島田, 欣二","creatorNameLang":"ja"},{"creatorName":"SHIMADA, Kinji","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"福重, 安雄","creatorNameLang":"ja"},{"creatorName":"FUKUSHIGE, Yasuo","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"留守, 成人","creatorNameLang":"ja"},{"creatorName":"RUSU, Shigeto","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"室屋, 道子","creatorNameLang":"ja"},{"creatorName":"MUROYA, Michiko","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":"2016-10-31"}],"displaytype":"detail","filename":"AN00040363_v23_p113-121.pdf","filesize":[{"value":"1.9 MB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"AN00040363_v23_p113-121.pdf","objectType":"fulltext","url":"https://ir.kagoshima-u.ac.jp/record/10700/files/AN00040363_v23_p113-121.pdf"},"version_id":"2f41e2cb-889e-4bdd-8b64-21c3506e03c2"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"シラスの工業的利用に関する研究（第17報） : シラスガラス－カルシア－マグネシア系ガラスの結晶化","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"シラスの工業的利用に関する研究（第17報） : シラスガラス－カルシア－マグネシア系ガラスの結晶化","subitem_title_language":"ja"},{"subitem_title":"STUDIES ON THE INDUSTRIAL APPLICATION OF SHIRASU (Report 17) : On the Crystallization of the Glass in the System Shirasu Volcanic Glass (SVG)-CaO-MgO","subitem_title_language":"en"}]},"item_type_id":"7","owner":"18","path":["36","5343"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2015-06-10"},"publish_date":"2015-06-10","publish_status":"0","recid":"10700","relation_version_is_last":true,"title":["シラスの工業的利用に関する研究（第17報） : シラスガラス－カルシア－マグネシア系ガラスの結晶化"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2024-02-20T05:02:01.042125+00:00"}
