Presents the outcome of intensive research into highly dispersed sodium‐aluminium silicate. Optimal conditions of the precipitation process of sodium‐aluminium silicates of high dispersion degrees from the solution of sodium metasilicate were given. In the precipitation process water soluble aluminium salts were used. A physicochemical analysis and microscopic structure of the obtained silicates were performed. The products obtained are characterized by parameters comparable to those of the sodium‐aluminium silicate P‐820 (Degussa).
