Abstract:
In this study, hydroxyapatite HA, [(Ca>o(P04)6(OHi:,j] was synthesized using wet chemical precipitation
technique at different reflux temperatures. Calcium hydroxide [Ca(OH)J powder and Phosphoric acid
[H3PO4] solution were used as starting materials. Variation in PH value of Ca(OHsuspension during the
addition of H}P04 solution was analyzed. The effect of reflux temperature for the synthesis HA was
investigated. Characteristics of synthesized powder were analyzed by Fourier transformed infrared (FTIR)
spectroscopy and X-ray dijfraction (XRD). The powder characteristic has demonstrated that, the reflux
temperature played an important role in the synthesis of pure and single phase HA powder.
