Sonochemical Synthesis of Hydroxyapatite Nanoparticles with Different Precursor Reagents

Different precursor chemicals ($3Ca(OH)_2,$ $Ca(NO_3)_2$ and $CaO$ as $Ca^{2+}$ sources, $H_3PO_4$ and $(NH_4)_2HPO_4$ as $PO_4^{3-}$ sources were used to synthesis of nanosized hydroxyapatite powder with ultrasonic precipitation method. The effect of different chemical precursors was investigated. Sample characterization was achieved by powder X-ray diffraction, the Fourier transformed infrared transmission spectroscopy, zeta sizer, scanning electron microscopy, density and surface area measurements
