In the presented study two procedures were suggested for the production of synthetic magnesium silicates, based on the classical precipitation and on the precipitation in the presence of non-ionic surfactants. The obtained products were subjected to a comprehensive physicochemical analysis in order to define their application spectrum. The morphology of synthetic magnesium silicates was defined by measuring their particle diameter (using the DLS approach) and examining their surface development (using SEM). Since the magnesium silicates were potentially considered to be applied as adsorbents and fillers, their adsorptive properties were also determined. For this purpose, nitrogen adsorption/desorption isotherms were determined for the surfaces of the precipitated synthetic silicates.
