Abstract:It is well known that the shape and size of inorganic nanostructures have much influence on their optical, electrical and physical properties. MgO is a promising material with potential applications in a variety of fields such as catalyst support, reinforcing reagent and good component in superconductors. In this study, flower-like Mg(OH)2 and cubic MgCO3 have been successfully prepared via hydrolysis control of magnesium salt and alkaline solution with common ions under hydrothermal condition by the formation of nano-platelets assembly. Subsequent calcination converts both Mg(OH)2 and MgCO3 into the corresponding MgO granules of similar flower-like and cubic morphology and size to each precursor. The physical and chemical properties of MgO and its precursors of Mg(OH)2 and MgCO3 are investigated by SEM, XRD, FT-IR, and TGA analysis.
