Abstract
Nano-scale powder of Magnesium (Mg) is found to play the dual role of catalyst and precursor with Boron-10 (B-10) in the synthesis of Magnesium diboride nanoparticles (Mg(10)B(2)NPs) at 800 degrees C. Catalytically, Mg softens and melts enriched Boron at a relatively lower temperature than its actual boiling point. As a precursor, it reacts with enriched Boron and forms the (MgB2)-B-10 compound. The nano-size catalyst and precursors help to grow the as-formed (MgB2)-B-10 compound in the form of nanoparticles. The shape or morphology of the synthesized Mg(10)B(2)NPs is revealed via field emission scanning electron microscopy (FESEM). Energy dispersive x-ray (EDX) spectroscopy has been performed to spot the elemental composition, whereas, X-ray diffraction (XRD), and X-ray photoelectron spectroscopy (XPS) are used to verify the composition and study the phase of the synthesized particles.
