The Role of the Solvent in Determining the Surface Texture of Magnesium Hydroxide

Abstract

The effect of the solvent on the surface properties of magnesium hydroxide was investigated in this study. The parameters examined were the effect of OH + /Mg2+ ratio, solvent composition and the ionic strength. The effect of the different variables was investigated by varying systematically some preparation conditions while keeping the others constant. The synthesized magnesium hydroxide samples physicochemical characteristics such as pore volume, specific surface area, pore size distribution, particle size and the amount of exchangeable -OH groups were found to be strongly influenced by the investigated preparation conditions. The powders were characterized by X Ray Diffraction (XRD), Thermogravimetric Analysis (TGA), Scanning Electron Microscopy (SEM) and Fourier Transform Infrared Spectroscopy FTIR.
