    Otherto give an aqueous solution of 4.0 to 12.0 wt % concentration of SiO2

Procedure

The following is an example of the preparation of a silica·alumina gel. JIS No. 3 water glass (content of silica as SiO2 : 28 wt %) is diluted with ion-exchanged water to give an aqueous solution of 4.0 to 12.0 wt % concentration of SiO2. Aluminum sulfate tetradecahydrate is dissolved in ion-exchanged water to give an aqueous solution of an aluminum sulfate concentration of 4.0 to 12.0 wt %.
