The main reason for forming composites is to improve the mechanical properties, most often toughness, above that of the stand-alone ceramic. For bioceramic composites we often are trying to increase A lc and decrease ...

The use of Engineering Ceramics, introduces entirely new fields to be considered. These include mechanical properties, decorative ceramics, environmental uses, energy applications, bioceramics, composites, functionally graded materials, intelligent ceramics and so on. 

Composite materials are used clinically in order to take advantage of the desirable properties of each of the constituent materials while limiting the undesirable or deleterious properties of the individual phases. Composites cover a wide range of compositions and representative materials are listed in Table VI. Most of what is discussed in this section will relate to bioceramic composites. Bioceramic composites are either bioinert, bioactive or biodegradable. Examples of each of these classes of composite and their applications are given in Table VII. 

As it has been exposed, the fundamental limitation by the application of the ceramic, glass and glass-ceramics are their low mechanical properties. In order to tiy to avoid these limitations was proposed the use of these materials as part of a composite material. Bioceramic composite synthesis serves the purpose of enhancing the mechanical behaviour of the parent ceramic, glass or glass-ceramic, while maintaining its excellent bioeompativility and bioactivity. 

Bioceramic composites can be divided in bioiner, bioactive and biodegradable and the ceramic phase can be the reinforcing material, the matrix or both. 

There are several bioceramic composite which have been manufaetures and used in clinical applications, the first bioactive composite was stainless steel/bioactive glass.
