Abstract:
Hydroxyapatite (Hap, Ca10(PO4)6(OH)2) is the major inorganic component in natural bones that crystallizes in hexagonal system. Hap has the advantages of excellent biocompatibility, free of cell toxicity and forming strong bonding to bone osteoinductively and due to that property it was widely studied and prepared in many forms for orthopedic and dental applications.The present paper describes the synthesis of hydroxyapatite ceramics powders via sol-gel method. The powders were sintered at 10000C. Energy-dispersive X-ray spectroscopy (EDXS), X-ray diffraction (XRD), transmission electron microscopy (TEM) and scanning electron microscopy (SEM) were used for characterization and evaluation of the elemental and phase composition, morphology and particle size of samples. The functional groups of the coatings were analyzed using Fourier transform infrared (FTIR). The XRD analysis revealed a well crystallized HAp structure at all temperatures.
