Experimental Investigation on the Characterization of HA/Alumina and HA/mgo Nanocomposites for Orthopedic Applications

Abstract

HA/Alumina and HA/MgO nanocomposites were successfully prepared by using the hydrothermal method for the first time at 250°C. The mechanisms of composite formation, crystallite size, crystallinity, morphology, were studied HA/Alumina and HA/MgO nanocomposites. XRD and FTIR investigations showed an intermolecular interaction between HA/Alumina and HA/MgO. The formation of HA/Alumina and HA/MgO nanocomposites are polycrystalline in nature. Mg incorporation into HA_P stimulates osteoblast proliferation. Mg acts similar to a growth factor during the early stages of osteogenesis and promotes bone formation. It confirmed in TEM analysis. TEM images further ascertained that HAP/Alumina was formed in a short nanorod shape and HA/MgO nanocomposites show nanocluster like morphology. The FTIR measurement shows the appropriate vibrational spectra of HA/Alumina and HA/MgO nanocomposites. The UV–VIS measurements show the band–gap of HA/Alumina and HA/MgO nanocomposites. This study provides a platform for further research on the HA/Alumina and HA/MgO nanocomposites for biomedical applications.
