Abstract
A process for preparing artificial bone is described which comprises: (i) preparing a mixture of a finely divided bio-compatible ceramic powder, an organic binder and a pore-forming agent in an inert liquid to form a body and causing at least some of the pore-forming agent to align along a common axis; (ii) optionally shaping the resulting body; (iii) allowing the pore-forming agent to form a porous structure in the body; (iv) heating the shaped body to a temperature sufficient to fix the porous structure and; (v) further heating the body to eliminate residues of organic binder and pore-forming agent and to fuse it.
