As the seed crystals were not placed compactly enough in the crucible, the crystal growth to the direction perpendicular to the cleavage plane was observed besides that which was parallel to the cleavage plane. The rate of the growth perpendicular to the cleavage plane in a mica crystal was been also reported to be about one hundredth of that which was parallel to the cleavage plane. In this paper, the crystal growth parallel to the cleavage plane and the growth perpendicular to the cleavage plane are reported. A) The crystal growth parallel to the cleavage plane. In the growth of a mica crystal, the seed booklet crystal is placed in the lower part of a platinum crucible and raw materials are put onto the seed crystal. A vertical electric furnace is used for heating. Rectangular crucibles of 5 mm × 5 mm, 7 mm × 7 mm, and 30 × 10 mm are used. With the lowering rate of the crucible four to ten times faster than the rate in the previous experiments, grown crystal booklets show almost the same transparency as those obtained in the previous experiments. The concentration of the etch pits with HF in the grown booklet crystals is also lower than the previous experiments and the satisfactory crystals are obtained. B) Crystal growth to the direction perpendicular to the cleavage plane. The crystal growth perpendicular to the cleavage plane of fluorphlogopite is not observed when the seed crystals are set in the crucible in such a way that the cleavage planes of seed crystals are horizontal. While, the crystal growth perpendicular to the cleavage planes is observed when the cleavage planes of seed crystals are vertical as well as parallel to the side wall of the crucible. The conditions of the growth are as follows ; The angle of elevation of the Y-shaped crucible : <45° Rate of lowering : <0.4mm/hr. Temperature gradient : <15℃/cm.","subitem_description_type":"Abstract"}]},"item_10_description_30":{"attribute_name":"資源タイプ（コンテンツの種類）","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_10_description_5":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"信州大学工学部紀要 24: 93-102 (1968)","subitem_description_type":"Other"}]},"item_10_publisher_4":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"信州大学工学部"}]},"item_10_source_id_35":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0037-3818","subitem_source_identifier_type":"ISSN"}]},"item_10_source_id_40":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00121228","subitem_source_identifier_type":"NCID"}]},"item_1627890569677":{"attribute_name":"出版タイプ","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":"大門,  信利","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"39912","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":"2015-09-28"}],"displaytype":"detail","filename":"Engineering24-08.pdf","filesize":[{"value":"863.4 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Engineering24-08.pdf","url":"https://soar-ir.repo.nii.ac.jp/record/13072/files/Engineering24-08.pdf"},"version_id":"b96d8b2f-dac1-40c0-96f4-c5893b2d20d4"}]},"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":"ルツボ降下法によるフッ素金雲母の育成","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ルツボ降下法によるフッ素金雲母の育成","subitem_title_language":"ja"},{"subitem_title":"Crystal Growth of Fluor-Phlogopite by the Stockbarger Technique","subitem_title_language":"en"}]},"item_type_id":"10","owner":"1","path":["1283"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2009-03-30"},"publish_date":"2009-03-30","publish_status":"0","recid":"13072","relation_version_is_last":true,"title":["ルツボ降下法によるフッ素金雲母の育成"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-03-16T05:05:41.585610+00:00"}
