Crystallographic Study of Hydroxyapatite Bioceramics Derived from Various Sources

Hydroxyapatite (HA) is a calcium phosphate based bioceramic material rich in hard tissues such as bones and teeth. It is used as an artificial bone substitute in orthopaedic and dental applications. It can be derived from synthetic or natural resources. It has all the characteristic features of biomaterials, in particular, crystallographic similarity with natural bone minerals. However, crystallographic properties HA prepared from various...
