Structural and Surface Morphological Change in Incorporation of Magnesium on Synthesised Nano Hydroxyapaptite

The complex apatite, Hydroxyapatite (Ca₁₀(Po₄)₆ (OH)₂) (HAp) has the hydroxyl group as end member with the Ca/P ratio 1.67. Nano Hydroxyapatite is mainly used in bone tissue engineering and dental applications. Magnesium is one of the predominant substitutes for calcium in biological apatites. Mg substituted nano Hydroxyapatite are expected to have excellent biocompatibility and properties that can be favourably compared with those of hard tissue, and it stimulates osteoblast proliferation. The aim of this study is to synthesis and characterize the pure nano Hydroxyapatite and Mg-doped nano Hydroxyapatite by sol-gel method. The functional group of the prepared samples were analyzed using Fourier Transform Infrared Spectroscopy (FTIR). The nature and particle size of the prepared samples were analyzed by the X-ray diffraction method (XRD). The surface morphology was analyzed using a scanning electron microscope (SEM).
