Abstract
(EN) Ceramic porous and non-porous articles are made by a process that includes a hardening step in which the liquid of a liquid-containing ceramic composition is extracted from the ceramic composition by exposing the ceramic composition to a solvent in which the liquid in the composition is soluble before the ceramic composition is solidified into the final ceramic article. Calcium phosphate porous ceramic articles of the invention are constructed and characterized that may be used as implants to repair bone defects.
(FR) La présente invention concerne des articles poreux et non poreux en céramique qui sont fabriqués par un procédé qui comprend une étape de durcissage dans laquelle le liquide d’une composition céramique contenant du liquide est extrait de la composition céramique par exposition de la composition céramique à un solvant dans lequel le liquide dans la composition est soluble avant que la composition céramique soit solidifiée en article de céramique final. Les articles poreux en céramique de phosphate de calcium de l’invention sont construits et caractérisés en ce qu’ils peuvent être utilisés en tant qu’implants pour réparer des défauts osseux.
