The modification of water glass with nanoparticles of metal oxides in organic solvents was attempted in the study. The results of investigations of moulding sands with water glass modified by nanoparticles of the selected metal oxides in organic solvents, are presented in the hereby paper [21]. Nanoparticles of ZnO, Al₂O₃ or MgO in methanol, ethanol or propanol solutions were applied as modifiers of binding agents. Colloidal solutions of the modifiers were introduced into water glass in the amounts of 3, 5 or 7 mass %. Influences of the applied modifier and organic solvents as well as the modifier fraction in the binder on the selected strength properties of moulding sands were tested. On the bases of the analyses of the obtained results the probable mechanism of the water glass modification with nanoparticles of metal oxides was proposed.
