The hydrodynamic radii of colloidal silica particles in the aqueous solutions were measured under various conditions of \(\mathrm{pH}\) and salt concentration by means of the dynamic light scattering technique. In the salt free solutions the observed hydrodynamic radius increased by \(1 \mathrm{~nm}
The process parameters of the formation colloidal silica via sodium silicate had been investigated in this article. Sodium ion of sodium silicate was removed by ion-exchanging to obtain the active silicic acid which was titrated to the solution of potassium hydroxide (KOH) to form the colloidal sili
