Title (EN) NOVEL CERAMIC PARTICLE COMPOSITE MATERIAL
(FR) NOUVEAU MATÉRIAU COMPOSITE DE PARTICULES DE CÉRAMIQUE
(JA) 新規なセラミック粒子複合材料
Abstract:
(EN) [Problem] To provide a ceramic particle releasable composite material that reduces biocompatibility reduction and solubility changes as much as possible and has calcium phosphate sintered particles having a smaller particle size. [Solution] A ceramic particle releasable composite material characterized by: being a composite material including ceramic particles and a base material; being a ceramic particle composite material having the ceramic particles and the base material chemically bonded or the ceramic particles physically attached to or embedded in the base material; the particle size of the ceramic particles being 10-700 nm; the ceramic particles being calcium phosphate sintered particles; and the ceramic particles not containing calcium carbonate.
(FR) [Problème] Fournir un matériau composite libérable de particules de céramique qui réduit autant que possible la réduction de biocompatibilité et les changements de solubilité et comporte des particules frittées de phosphate de calcium ayant une taille de particule plus petite. [Solution] La présente invention concerne un matériau composite libérable de particules de céramique caractérisé en ce que : il est un matériau composite comprenant des particules de céramique et un matériau de base ; il est un matériau composite de particules de céramique comportant les particules de céramique et le matériau de base liés chimiquement ou les particules de céramique physiquement fixées à ou incorporées dans le matériau de base ; la taille de particule des particules de céramique est de 10 à 700 nm ; les particules de céramique sont des particules frittées de phosphate de calcium ; et les particules de céramique ne contiennent pas de carbonate de calcium.
(JA) 【課題】 生体親和性低下や溶解性変化が極力抑制され、且つ、より小さい粒径のリン酸カルシウム焼結体粒子を有するセラミック粒子剥離性複合材料の提供。 【解決手段】 セラミック粒子と基材とを含む複合材料であって、前記セラミック粒子と前記基材とが化学結合しているか又は前記セラミック粒子が前記基材に物理的に付着しているかもしくは埋設されたセラミック粒子複合材料であって、前記セラミック粒子の粒子径が、10nm~700nmの範囲内であり、前記セラミック粒子が、リン酸カルシウム焼結体粒子であり、前記セラミック粒子が、炭酸カルシウムを含有しないことを特徴とするセラミック粒子剥離性複合材料。
