Beschreibung
Zusammenfassung:	The invention concerns a method for preparing silica sols with reduced aggregation and/or agglomeration rate, comprising synthesis of silica sols by reacting in solution a silicate with an acidifying agent. The invention is characterised in that during said synthesis, it consists in reducing in parallel the amount of salts present in the reaction solution, by electrodialysis of said solution in an apparatus (3).
