- In the present work, Hydroxyapatite synthesis was carried out using hydrothermal method with calcium nitrate tetrahydrate (Ca(NO3)2.4H2O) and fosfor pentaoksit (P2O5) as precursors. For the hydrothermal method, constant reaction temperature (180°C) and different reaction times (6 hours, 12 hours, 18 hours and 24 hours) were determined. The samples produced were divided into two groups. Four samples were not heat treatment; four samples were heat treatment at 700°C for 1 hour. The obtained products were characterized by scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS) techniques, X-ray diffraction (XRD) and UV-Vis spectrometer. SEM photos showed that the Hydroxyapatite powders produced are in the form of the agglomerate. According to EDS results, Hydroxyapatite samples are of high purity. XRD’s findings confirm that the diffraction peaks correspond to the pure phase of Hydroxyapatite. A general decrease was observed in the energy band gap of the samples with increasing hydrothermal reaction time.
