Silica particles grew larger at lower reaction temperatures. A linear correlation was observed between concentration of ammonia in the range of 0.5-4.0mol/l and average particle size of the silica. Plots of particle size against the concentration of water showed a maximum at about 8mol/l. Under a constant concentration of amine derivative, the growth rate of silica particles increased in the following order; (C_2H_5)_3N<(CH_3)_3N<(C_2H_5)_2NH<(CH_3)_2NH<CH_3NH_2. The diameter of silica spheres decreased to 3/4 of its initial diameter by heating to 1000°C through a two step dehydratio process. A rainbow-colored precipitate, in which silica spheres were close-packed in an ordered array, was obtained by allowing the solution containing monodispersed silica spheres to stand at room temperature for 3 months.","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":"458","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":"平田, 好洋","creatorNameLang":"ja"},{"creatorName":"HIRATA, Yoshihiro","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"西牟田, 幸治","creatorNameLang":"ja"},{"creatorName":"NISHIMUTA, Koji","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":"2016-10-27"}],"displaytype":"detail","filename":"AN00040363_v26_p53-59.pdf","filesize":[{"value":"1.8 MB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"AN00040363_v26_p53-59.pdf","objectType":"fulltext","url":"https://ir.kagoshima-u.ac.jp/record/4552/files/AN00040363_v26_p53-59.pdf"},"version_id":"143b83d3-cf0b-425d-8dc1-35d671d0e109"}]},"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":"火山作用と関係ある無定形ケイ酸の性質とその応用的研究 : 第34報オパール状物質の合成 (その2)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"火山作用と関係ある無定形ケイ酸の性質とその応用的研究 : 第34報オパール状物質の合成 (その2)","subitem_title_language":"ja"},{"subitem_title":"Studies on the properties of amorphous silica having some connection with volcanic action and its industrial application (Report 34) : synthesis of opal-like material (II)","subitem_title_language":"en"}]},"item_type_id":"7","owner":"18","path":["36","5345"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2015-06-09"},"publish_date":"2015-06-09","publish_status":"0","recid":"4552","relation_version_is_last":true,"title":["火山作用と関係ある無定形ケイ酸の性質とその応用的研究 : 第34報オパール状物質の合成 (その2)"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2024-02-20T04:58:43.017290+00:00"}
