Method for preparing silica nanoparticles |
| abstract |
A method for preparing silica nanoparticles includes the steps of: slowly titrating a sodium silicate solution with an acid solution to obtain a silicic acid-containing solution; continuously stirring the silicic acid-containing solution; slowly titrating the silicic acid-containing solution with the acid solution to obtain a silicic acid-enriched solution; continuously stirring the silicic acid-enriched solution; collecting the silicic acid-enriched solution as a silica nanoparticle precursor solution when a pH value of the silicic acid-enriched solution reaches a target pH value; and subjecting the silica nanoparticle precursor solution to a flame spray pyrolysis or a drying-grinding-calcining treatment. |
