Abstract

HA/Alumina and HA/MgO nanocomposites were successfullyprepared by using the hydrothermal method for the first time at 2500C.The mechanisms of composite formation, crystallite size, crystallinity,morphology were studied for HA/Alumina and HA/MgOnanocomposites. XRD and FTIR investigations showed anintermolecular interaction between HA/Alumina and HA/MgO. Theformation of HA/Alumina and HA/MgO nanocomposites arepolycrystalline in nature. It confirmed in TEM analysis. TEM imagesfurther ascertained that HA/Alumina were formed in a short nanorodshape and HA/MgO nanocomposites show nanocluster likemorphology. The FTIR measurement shows the appropriate vibrationalspectra of HA/Alumina and HA/MgO nanocomposites. The UV-VIS measurements show theband-gap of HA/Alumina and HA/MgO nanocomposites. This study provides a platform forfurther research on the HA/Alumina and HA/MgO nanocomposites for biomedicalapplications.
