Setting time, setting expansion and compressive strength were affected by the particle size, and content of metal oxide and phosphate. The pH of the slurry changed during the reaction from neutral to alkaline. Reusage of phosphate bonded investment material was studied from the stand point of environmental contamination. Used investment materials were added 5, 10 and 15% to four kinds of phosphate investment products. The effects of addition to each phosphate investment product were measured for setting expansion, compressive strength and casting accuracy. Results were as follows: 1) Setting expansion decreased due to the addition of used investment materials of GC, FU and SO investment material. 2) Heat expansion increased due to the addition of used investment materials of GC, FU and WM investment material. 3) Compressive strength increased due to the addition of used investment materials of GC, SO and WM investment material. 4) The addition of used investment materials to GC and WM investment material did not affect the casting accuracy. However when added to SO and FU investment material, the casting accuracy was not satisfactory.","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":"伊藤, 充雄"},{"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_13-02-03.pdf","filesize":[{"value":"340.3 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"matsumoto_shigaku_13-02-03.pdf","url":"https://mdu.repo.nii.ac.jp/record/1250/files/matsumoto_shigaku_13-02-03.pdf"},"version_id":"1f3296e6-58fa-4063-b863-5008a12ce8ee"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"鋳造","subitem_subject_scheme":"Other"},{"subitem_subject":"鋳型","subitem_subject_scheme":"Other"},{"subitem_subject":"精度","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":"リン酸塩系埋没材について(その7)歯科鋳造用埋没材の再利用について","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"リン酸塩系埋没材について(その7)歯科鋳造用埋没材の再利用について"}]},"item_type_id":"2","owner":"3","path":["74"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-05-24"},"publish_date":"2012-05-24","publish_status":"0","recid":"1250","relation_version_is_last":true,"title":["リン酸塩系埋没材について(その7)歯科鋳造用埋没材の再利用について"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-19T08:18:46.027040+00:00"}
