Abstract

Two simple methods for the synthesis of Mg(OH) ₂ nanostructures, MgO nanoflakes and MgO/Mg(OH) ₂ nanocomposite using a conventional microwave oven are reported. The first method includes the preparation of Mg(OH) ₂ by a simple reaction of magnesium powder with deionized water under microwave radiation. The second approach relates to the transformation of Mg(OH) ₂ to MgO nanoflakes and grass-like nanostructures by rapid microwave hybrid heating using a SiC-based composite susceptor. The as-synthesized samples have been characterized by X-ray diffraction (XRD) and Field Emission Scanning Electron Microscope (FESEM) The optical properties of the samples are investigated using UV-visible spectroscopy to study the reflective index and optical dielectric constant.
