Hydroxyapatite (HA), which is represented by the formula
Ca10(PO4)6(OH)2, is one of the inorganic components of the hard tissues of
living bodies such as bones, teeth, etc. HA is a calcium phosphate-based
bioceramic, which has been used in medicine and dentistry for more than 20
years because of its excellent biocompatibility with human tissues. The
precipitation process, considered here, can add orthophosphoric acid solution
to a calcium hydroxide solution. The precipitated powder samples were
examined by XRD, FTIR, SEM and FESEM (Field emission electron
microscopy) methods. The results revealed that the final precipitated powder
is HA and using SEM with high magnification showed that these HA
consists of small rod-like particles. In addition, the morphology and size of
the precipitated particles change during different stages of process. After
drying, these nano-particles tend to form small agglomerates.
