摘要

Hydroxyapatite, a naturally occurring form of calcium phosphate, is the main mineral component of bones and teeth. Natural hydroxyapatite and bone have similar physical and chemical characteristics make it biocompatible. Its porous structure resembles native bone. The biocompatibility, biodegradability and bioactivity make it extensively useful in interdisciplinary fields of sciences like chemistry, biology, and medicine. Calcium phosphate-based ceramics are of great interest as substitutes of synthetic bone graft due to their similarities in composition to bone mineral and bioactivity as well as osteoconductivity. This article gives an overview of hydroxyapatite from its preparation and properties to biomedical applications of its composites.
