Abstract
A process is provided for producing a bioceramic composite in which an alumina based ceramic substrate is coated with an intermediate calcium pyrophosphate layer to cement a porous calcium phosphate material to the alumina based ceramic substrate. In one aspect of the invention, the porous calcium phosphate material is a porous lattice made from natural bone. A bioceramic composite which includes an alumina-based ceramic substrate, an intermediate calcium pyrophosphate layer and a porous natural bone material bonded to the intermediate calcium pyrophosphate layer is also disclosed.
