Abstract
Hydroxyapatite powders were prepared after heating at $1250^{\circ}C$ by the direct reaction using oyster shells and $H_3$$PO_4$. Properties of hydroxyapatite powders were investigated as XRF, XRD, DTA, FT-IR, SEM. Only hydroxyapatite was observed in XRD powders which was heated at $1250^{\circ}C$ for 2 hours and there was no remained CaO in that sample. And the results of FT-IR of sample was confirmed hydroxyapatite. Sample was agglomerated together, but needle shape morphology was observed in powders heated at $1250^{\circ}C$.
