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

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 viscosity behavior of aqueous suspensions of silica particles with physically adsorbed polyethylene oxide (PEO) molecules was investigated in relation to the adsorbed layer density and concentration of nonadsorbed polymer in the suspending fluid. Adsorption studies revealed the presence of two p
