| Abstract: | A new process for producing high - purity silica from silicofluoric acid is introduced . Silicofluoric acid reacted with ammonium hydrocarbonate to obtain ammonium silicofluoric acid, which then reacted with ammonium hydrocar-bonate to make silica. The intermediate product was washed with water, then was dried and sintered to the final product. The factors influencing the purity of the title product have been investigated. |
