Nanocrystalline magnesium oxide with plate-like shape was prepared by a wet chemical synthesis method using
polyvinyl alcohol as surfactant. The synthesized samples were characterized by N2 adsorption (BET), X-ray Diffraction
(XRD), Transmission electron microscopy (TEM) and Fourier Transform Infrared (FTIR) analyses. The obtained
results showed that the addition of surfactant has a significant effect on the structural properties of magnesium oxide
and led to obtain a powder with higher specific surface area and smaller crystallite size. The specific surface area
increased with decreasing in metal ion to PVA monomer unit mole ratio (MgO/PVA). Transition electron microscopy
(TEM) showed a structure consisting of aggregates or agglomerates of particles forming slit shaped pores (plates or
edged particles like cubes).
