Методика

About 100 parts by weight of granular sodium metasilicate containing less than 6 mols of water per mol of sodium metasilicate is slowly added to 100 parts by weight of concentrated sulfuric acid while agitating and keeping the temperature below 100° C. The chemical reaction is complete in 1 to 2 hours, thereby producing a white granular silicic acid compound and sodium hydrogen sulfate. The mixture is washed with water, filtered to remove the sodium hydrogen sulfate and recover the white granular silicic acid compound. The silicic acid compound is air dried at 25° to 75° C by blowing air thru the granules.
