TiB₂was formed at 897 K or more, and its X-ray diffraction intensity increased with increasing temperature. In addition to MgO and MgTi₂O₄, which were main by-products, Mg₃(BO₃）₂ and (Mg, Ti) O were produced at lower temperature and at higher temperature, respectively. In the magnesio-thermic reduction of TiO₂, Ti₂, O was identified at 1273 K or more, and its X-ray diffraction intensity increased to a maximum at 1373 K, but finally disappeared at 1573 K. In reduction of short time period, however, the formation of TiO₂ was observed even at 1573 K. On the other hand, in the magnesio-thermic reduction of B₂O₃, the formation of boron could not be identified by X-ray diffraction, but weak diffraction peaks of B₄C were detected. It was inferred from these results that amorphous boron had been formed. Thermodynamic consideration clarified that TiO₂is easily reduced to TiO with magnesium, but the additional reduction of TiO to Ti is difficult at higher temperature. Therefore, since the formation of boron precedes in the simultaneous magnesio-thermic reduction of TiO₂- B₂O₃ mixture, it was concluded that TiB₂is finally formed according to the next reaction : TiO + Mg + 2B = TiB₂ + MgO.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_77_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":"平井 伸治（HIRAI Shinji）","subitem_link_url":"http://rdsoran.muroran-it.ac.jp/html/100000177_ja.html"}]},"item_77_publisher_11":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"室蘭工業大学","subitem_publisher_language":"ja"}]},"item_77_relation_15":{"attribute_name":"論文ID（NAID）","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"40003627716","subitem_relation_type_select":"NAID"}}]},"item_77_rights_19":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"© 1991 室蘭工業大学","subitem_rights_language":"ja"}]},"item_77_source_id_12":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"05802415","subitem_source_identifier_type":"PISSN"}]},"item_77_source_id_14":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00238225","subitem_source_identifier_type":"NCID"}]},"item_77_subject_9":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"431.37","subitem_subject_scheme":"NDC"}]},"item_77_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":[{"creatorAffiliations":[{"affiliationNameIdentifiers":[],"affiliationNames":[{"affiliationName":""}]}],"creatorNames":[{"creatorName":"平井,  伸治","creatorNameLang":"ja"},{"creatorName":"HIRAI, Shinji","creatorNameLang":"en"},{"creatorName":"ヒライ, シンジ","creatorNameLang":"ja-Kana"}],"familyNames":[{},{},{}],"givenNames":[{},{},{}],"nameIdentifiers":[{},{}]},{"creatorAffiliations":[{"affiliationNameIdentifiers":[],"affiliationNames":[{"affiliationName":""}]}],"creatorNames":[{"creatorName":"土屋, 美智昭","creatorNameLang":"ja"},{"creatorName":"TSUCHIYA, Michiaki","creatorNameLang":"en"},{"creatorName":"ツチヤ, ミチアキ","creatorNameLang":"ja-Kana"}],"familyNames":[{},{},{}],"givenNames":[{},{},{}],"nameIdentifiers":[{}]},{"creatorAffiliations":[{"affiliationNameIdentifiers":[],"affiliationNames":[{"affiliationName":""}]}],"creatorNames":[{"creatorName":"片山,  博","creatorNameLang":"ja"},{"creatorName":"カタヤマ, ヒロシ","creatorNameLang":"ja-Kana"},{"creatorName":"KATAYAMA, Hiroshi","creatorNameLang":"en"}],"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":"2016-02-16"}],"displaytype":"detail","filename":"kiyo41_rikou_pp61-69.pdf","filesize":[{"value":"1.0 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"kiyo41_rikou_pp61-69.pdf","objectType":"fulltext","url":"https://muroran-it.repo.nii.ac.jp/record/8170/files/kiyo41_rikou_pp61-69.pdf"},"version_id":"604248f3-2109-4a1b-a5fa-40d1e5700d78"}]},"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":"TiO₂- B₂O₃混合物のMg熱還元によるTiB₂の生成反応","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"TiO₂- B₂O₃混合物のMg熱還元によるTiB₂の生成反応","subitem_title_language":"ja"},{"subitem_title":"Formation of TiB₂by Magnesio -thermic Reduction of TiO₂- B₂O₃Mixture.","subitem_title_language":"en"}]},"item_type_id":"77","owner":"18","path":["159","248"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2014-03-04"},"publish_date":"2014-03-04","publish_status":"0","recid":"8170","relation_version_is_last":true,"title":["TiO₂- B₂O₃混合物のMg熱還元によるTiB₂の生成反応"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2024-01-25T02:43:55.531358+00:00"}
