The present invention provides a ceramic porous body for in-vitro and in-vivo use comprising a composition comprising a calcium aluminate (CA) containing phase and optionally at least one of an accelerator, a retarder, a surfactant, a foaming agent, a reactive alumina, water, a fiber, and a biologically active material, and combinations thereof. Ceramic compositions are provides as well as method of using the ceramic compositions and methods of manufacturing a ceramic porous body. The ceramic porous bodies of this invention may be used as artificial bones, joints, in-vitro support structures, and in-vivo support structures for cells, tissues, organs, and nerve growth and regeneration.
L'invention se rapporte à un corps poreux céramique qui s'utilise in-vitro et in-vivo, comprenant une composition qui contient une phase contenant un aluminate de calcium et facultativement au moins un accélérateur, un retardateur, un agent de surface, un agent moussant, de l'alumine réactive, de l'eau, une fibre, et un matériau biologiquement actif, et des combinaisons de ceux-ci. L'invention porte sur des compositions céramiques et sur des procédés d'utilisation des compositions céramiques ainsi que sur des procédés de fabrication d'un corps céramique poreux. Ces corps céramiques poreux de l'invention peuvent servir d'os, d'articulations artificiels, de structures de support in-virto et de structures de support in-vivo artificiels pour des cellules, des tissus, des organes ainsi que la croissance nerveuse et la régénération.
