A mixture of the silica powder and milk of lime (calcined CaCO_3) was stirred in a teflon container of autoclave and treated hydrothermally under the following conditions; molar ratio of Cao/SiO_2 1.05, weight ratio of water/solid 5 to 30, and temperature 80°-250°C foo 1 to 50 h. Effect of firing temparature of raw silica and CaCO_3, additive of heavy metal ions such as Ni^{2+}, Cr^{3+} and Fe^{3+}, and the condition of reaction on the phase of products and the morphology was examined using the X-ray powder diffraction test (XRD), the differential thermal analysis (DTA), the thermal gravimetric analysis (TGA), the infra-red absorption spectroscopy (IR), and electron microscopy. The results showed that the products treated hydrothermally above l80°C were C-S-H(CaO-SiO_2-H_2O), α-C_2SH(2CaO･SiO_2･H_2O), tobermorite(6CaO･5SiO_2･6H_2O) and xonotlite(6CaO・6SiO_2･H_2O), \nespecially promoted by the addition of Cr^{3+} in tobermorite and promoted with increasing of crystlline silica (cristobalite) by calcination in xonotlite.","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"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"松下, 浩司","creatorNameLang":"ja"},{"creatorName":"MATSUSHITA, 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_v28_p125-135.pdf","filesize":[{"value":"1.5 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AN00040363_v28_p125-135.pdf","objectType":"fulltext","url":"https://ir.kagoshima-u.ac.jp/record/682/files/AN00040363_v28_p125-135.pdf"},"version_id":"ae0a28a5-5a2f-42f6-b828-0b485f25f48b"}]},"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35報 オパール質ケイ石を原料とするケイ酸石灰塩水和物の合成","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35報 オパール質ケイ石を原料とするケイ酸石灰塩水和物の合成","subitem_title_language":"ja"},{"subitem_title":"Studies on the properties of amorphous silica having some connection with volcanic action and its industrial application : report XXXV on the synthesis of calcium silicate hydrates from opaline silica stone","subitem_title_language":"en"}]},"item_type_id":"7","owner":"18","path":["36","5348"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2015-06-08"},"publish_date":"2015-06-08","publish_status":"0","recid":"682","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35報 オパール質ケイ石を原料とするケイ酸石灰塩水和物の合成"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2024-02-20T04:56:57.427639+00:00"}
