A Comparative Study on Magnesium Hydroxide and Magnesium Oxide Nanostructures

Mg(OH)(2) and MgO nano particles having flake, like morphology have been synthesized using hydrothermal method. XRD pattern revealed the formation of hexagonal phase for Mg(OH)(2) while cubic phase for MgO. SEM images shows the transformation of morphology from nanoflakes to nanoballs like shape upon change in crystal structure from hexagonal Mg(OH)(2) to cubicMgO. Thermal decomposition and percentage weight loss were calculated through thermogravimetric analysis (TGA) and it is inferred that defects related to oxygen vacancies are responsible for the magnetic propertiesand the origin of d(0) ferromagnetism in these non-magnetic oxides.
