Quantitative analysis of the metal elements released in solutions was performed by I.C.P. method. The amounts of released metal was studied on the relation ship of alloying methods and casting methods. The results obtained were as follows: 1. Release of metal elements from 18K gold alloys (without zinc) is caused by copper oxide (Cu_2o), which was oxidized at alloying and casting in the atomsphere. 2. Tamman's discorrosion rule is ineffective on melting metal. Only deoxidization materials pprevent oxidation of gold alloys. 3. The oxides produced at melting time mix in castings, without exception. 4. If mixed oxides are unstable, the release of metal elements rise 100-10000 fold. 5. All dental castings should be cast in the total absens of oxygen. If impossible, then all dental alloys should contain deoxidization materials.","subitem_description_type":"Abstract"}]},"item_2_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"松本歯科大学学会"}]},"item_2_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00232590","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0385-1613","subitem_source_identifier_type":"ISSN"}]},"item_2_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":"永沢, 栄"},{"creatorName":"綿谷, 晃"},{"creatorName":"洞沢, 功子"},{"creatorName":"高橋, 重雄"}],"nameIdentifiers":[{"nameIdentifier":"0","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2012-05-24"}],"displaytype":"detail","filename":"matsumoto_shigaku_17-01-07.pdf","filesize":[{"value":"4.3 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"matsumoto_shigaku_17-01-07.pdf","url":"https://mdu.repo.nii.ac.jp/record/1077/files/matsumoto_shigaku_17-01-07.pdf"},"version_id":"0fcce3ea-5093-43cf-9750-8af10b386529"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"腐食","subitem_subject_scheme":"Other"},{"subitem_subject":"溶出","subitem_subject_scheme":"Other"},{"subitem_subject":"18K金合金","subitem_subject_scheme":"Other"},{"subitem_subject":"鋳造方法","subitem_subject_scheme":"Other"},{"subitem_subject":"酸化第1銅","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":"18K金合金の耐食性に関する研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"18K金合金の耐食性に関する研究"}]},"item_type_id":"2","owner":"3","path":["87"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-05-24"},"publish_date":"2012-05-24","publish_status":"0","recid":"1077","relation_version_is_last":true,"title":["18K金合金の耐食性に関する研究"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-19T08:22:57.917766+00:00"}
