Powder samples that were suspended in the ten percent acid solution of HCl，H_2SO_4，HNO_3 or H_3PO_4，were treated 3 hours in the autoclave at 150°C. After the hydrothermal acid treatment，samples were heated 2 hours at l300°C. By the X-ray\ndifraction method，it was made examination of the effect of hydrothermal acid treatment on the conversion of natural amorphous silica to crystalline. As the results，it was found that the rate of conversion of amorphous to crystalline silica \nwas strongly influenced by the hydrothermal acid treatment. The rate of amorphous to crystalline silica was stimulated by HCl，but was retarded by oxy-acid such as H_2SO_4，HNO_3，H_3PO_4.","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"},{"subitem_subject":"430","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"}]}]},"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_v2_p155-159.pdf","filesize":[{"value":"2.4 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AN00040363_v2_p155-159.pdf","objectType":"fulltext","url":"https://ir.kagoshima-u.ac.jp/record/2116/files/AN00040363_v2_p155-159.pdf"},"version_id":"f78cad80-394f-4cf4-8881-f3770c3a5ca4"}]},"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30報 天然産無定形ケイ酸の結晶化におよぼす水熱酸処理の影響","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30報 天然産無定形ケイ酸の結晶化におよぼす水熱酸処理の影響","subitem_title_language":"ja"},{"subitem_title":"STUDIES ON THE PROPERTIES OF AMORPHOUS SILICA HAVING SOME CONNECTION WITH THE VOLCANIC ACTION AND ITS INDUSTRIAL APPLICATION : XXX ON THE EFFECT OF HYDROTHERMAL ACID TREATMENT UPON THE CONVERSION OF NATURAL AMORPHOUS SILICA TO CRYSTALLINE","subitem_title_language":"en"}]},"item_type_id":"7","owner":"18","path":["36","5297"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2015-06-24"},"publish_date":"2015-06-24","publish_status":"0","recid":"2116","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30報 天然産無定形ケイ酸の結晶化におよぼす水熱酸処理の影響"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2024-02-20T04:57:02.952985+00:00"}
