Title (EN) METHOD FOR MANUFACTURING CALCIUM OCTAVUS PHOSPHATE MOLDED ARTICLE
(FR) PROCÉDÉ DE PRODUCTION D'UN ARTICLE MOULÉ EN PHOSPHATE D'OCTAVUS DE CALCIUM
(JA) 第八リン酸カルシウム成形体の製造方法
Abstract:
(EN) The present invention provides a method, etc., for manufacturing a molded article containing calcium octavus phosphate having a volume of 2.0 mm3 or more, the method being characterized in that: a precursor ceramic composition that includes Ca and/or PO4, has a solubility in H2O greater than that of calcium octavus phosphate, and has a volume greater than 2.0 mm3, is immersed in a solution including a composition not included in the precursor ceramic composition, among compositions of Ca, PO4, and H2O that are compositions of calcium octavus phosphate; the precursor ceramic composition is reacted; and at least a part of the precursor ceramic composition is converted into calcium octavus phosphate.
(FR) La présente invention concerne un procédé, etc., de production d’un article moulé contenant du phosphate d'octavus de calcium possédant un volume égal ou supérieur à 2,0 mm3, le procédé étant caractérisé en ce que : une composition de céramique précurseur qui comprend Ca et/ou PO4, qui possède une solubilité dans H2O supérieure à celle du phosphate d'octavus de calcium et qui possède un volume supérieur à 2,0 mm3, est immergée dans une solution comprenant une composition non comprise dans la composition de céramique précurseur, parmi des compositions de Ca, PO4 et H2O qui sont des compositions de phosphate d'octavus de calcium ; la composition de céramique précurseur est mise en réaction ; et au moins une partie de la composition de céramique précurseur est convertie en phosphate d'octavus de calcium.
(JA) 本発明は、Ca及びPOの少なくとも1つを組成に含み、HOへの溶解度が第八リン酸カルシウムより高く、体積が2.0mm超の前駆体セラミックス組成物を、第八リン酸カルシウムの組成であるCa、PO、HOの組成のうち前記前駆体セラミックス組成物に含まれない組成を含む溶液に浸漬し、前記前駆体セラミックス組成物を反応させて、前記前駆体セラミックス組成物の少なくとも一部を第八リン酸カルシウムへ変換することを特徴とする、体積が2.0mm以上の第八リン酸カルシウムを含む成形体の製造方法等を提供する。
