Abstract

MgO nanoparticles (MgONps) were prepared by the rapid anodizing method (RBA). The properties of these particles were tested by X-ray diffraction (XRD) and Scanning electron microscope (SEM). MgO powder had a polycrystalline structure with a dominant peak (200). MgONps had a spherical shape with a diameter of ~ 30 nm. To test the ability of this material to stimulate bone like apatite, these particles were deposited on a Ti base by electrophoretic deposition (EPD) method and then dipped in simulated body fluid (SBF) for one month. The formation of hydroxyapatite (HAp) on MgONps after 30 days was proved through the appearance of several HAp peaks in the XRD pattern of the sample. SEM images showed that HAp was in the form of nanoballs connected to each other. According to the Energy dispersive X-ray spectroscopy (EDX) test wt% for Ca and P were 32.8 and 23.3 respectively.
