Room-temperature phosphorylation and subsequent calcination produce pure HAp via intermediate amorphous calcium phosphate (ACP). The pre-calcined sample undergoes a competitive transformation from ACC to ACP and crystalline calcium carbonate. The water content, ACC concentration, Ca/P molar ratio, and pH during the phosphorylation reaction play crucial roles in the final phase of the crystalline phosphate compound. Pure HAp is formed after ACP is transformed from ACC at a low concentration (1 wt%) of ACC colloid (1.71 < Ca/P < 1.88), whereas Ca/P = 1.51 leads to pure beta-tricalcium phosphate. The ACP phases are precursors for calcium phosphate compounds and may determine the final crystalline phase.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_79_link_17":{"attribute_name":"出版者版へのリンク","attribute_value_mlt":[{"subitem_link_text":"10.1038/s41598-021-91064-y","subitem_link_url":"https://doi.org/10.1038/s41598-021-91064-y"}]},"item_79_link_5":{"attribute_name":"室蘭工業大学研究者データベースへのリンク","attribute_value_mlt":[{"subitem_link_text":"神田 康晴（KANDA Yasuharu）","subitem_link_url":"http://rdsoran.muroran-it.ac.jp/html/100000202_ja.html"},{"subitem_link_text":"山中 真也（YAMANAKA Shinya）","subitem_link_url":"http://rdsoran.muroran-it.ac.jp/html/100000163_ja.html"}]},"item_79_publisher_11":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"NATURE PORTFOLIO","subitem_publisher_language":"en"}]},"item_79_relation_18":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1038/s41598-021-91064-y","subitem_relation_type_select":"DOI"}}]},"item_79_rights_19":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"https://creativecommons.org/licenses/by/4.0/","subitem_rights_language":"en"}]},"item_79_source_id_12":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2045-2322","subitem_source_identifier_type":"EISSN"}]},"item_79_subject_9":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"430","subitem_subject_scheme":"NDC"}]},"item_79_version_type_21":{"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_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Sawada, Michika","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Sridhar, Kandi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorAffiliations":[{"affiliationNameIdentifiers":[{}],"affiliationNames":[{},{}]}],"creatorNames":[{"creatorName":"KANDA,  Yasuharu","creatorNameLang":"en"},{"creatorName":"カンダ, ヤスハル","creatorNameLang":"ja-Kana"},{"creatorName":"神田, 康晴","creatorNameLang":"ja"}],"familyNames":[{},{},{}],"givenNames":[{},{},{}],"nameIdentifiers":[{},{}]},{"creatorAffiliations":[{"affiliationNameIdentifiers":[{}],"affiliationNames":[{},{}]}],"creatorNames":[{"creatorName":"山中,  真也","creatorNameLang":"ja"},{"creatorName":"YAMANAKA, Shinya","creatorNameLang":"en"},{"creatorName":"ヤマナカ, シンヤ","creatorNameLang":"ja-Kana"}],"familyNames":[{},{},{}],"givenNames":[{},{},{}],"nameIdentifiers":[{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2022-03-23"}],"displaytype":"detail","filename":"SciRep_11_11546.pdf","filesize":[{"value":"1.8 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SciRep_11_11546","objectType":"fulltext","url":"https://muroran-it.repo.nii.ac.jp/record/10522/files/SciRep_11_11546.pdf"},"version_id":"59adb8fa-1c9b-4370-aed7-2bfda1e08102"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"Pure hydroxyapatite synthesis originating from amorphous calcium carbonate","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Pure hydroxyapatite synthesis originating from amorphous calcium carbonate","subitem_title_language":"en"}]},"item_type_id":"79","owner":"18","path":["46","300","380"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2022-03-23"},"publish_date":"2022-03-23","publish_status":"0","recid":"10522","relation_version_is_last":true,"title":["Pure hydroxyapatite synthesis originating from amorphous calcium carbonate"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2023-11-06T06:42:19.583521+00:00"}
