ABSTRACT:
Nanosized hydroxyapatite ?(Ca10(Po4)6(OH)2 or HA)? was prepared by wet-chemical precipitation route by using calcium chloride dihydrate CaCl2.2H2O and disodium hydrogen phosphate Na2HPO4 for different concentration of the starting solution. The prepared samples were characterized by the use of X-ray diffraction (XRD) and it confirms the hexagonal structure of HAp. By using Scherer formula the detailed structural analyses such as crystallite size, strain and dislocation density were estimated for as-prepared samples. As the concentration of the sample increases the crystallite size increases whilestrain and dislocation density decrease. The crystalline size of as-prepared nanoHAp ranges from 14 to 33 nm. Field emission scanning electron microscopy (FE-SEM) shows the agglomerated grains in all samples. The energy dispersive X-ray (EDX) spectra confirm the presence of Ca, P and O in HAp. The FTIR and Raman spectra confirm characteristic vibration peaks at 561 cm-1 and 962 cm-1 of phosphate bands of HAP respectively.
