Synthesis of magnesium hydroxide using different magnesium salts and ammonium hydroxide is described. The reaction was performed in the presence of non-ionic compounds representing the group of poly(ethylene glycols) as modifiers. Dispersive properties of the products were characterised by polydispersity index, particle size, as well as SEM and TEM images. Adsorptive properties of the products were evaluated on the basis of their specific surface area, pore volume and diameter determination. Physicochemical characterisation of the products was extended by the degrees of their surface coverage with PEG, calculated on the basis of elemental analysis and specific surface area BET. Crystalline structures of the products were determined by the WAXS method and then using the Scherrer formula the crystallite size was calculated for selected samples. Wettability profiles in aqueous systems were measured and selected samples were subjected to TG/DTA analyses. The properties of the products were found to be significantly dependent on the molecular mass of PEG and type of magnesium salt used.
