摘要：
A process for the recovery of nanoporous silica and sodium fluoride from hexafluorosilicic acid and sodium silicate under the different molar ratios was studied. In order to prepare the appropriate solutions of initial compounds 25% of hexafluorosilicic acid and the 18% of sodium silicate were used. Obtained nanoporous silica and sodium fluoride have been characterized by XRD, BET, TGA, EDX and SEM.
