Aqueous Colloidal Silica Manufacturing Process.

Colloidal silica, also known as Silica Sol, is a stable dispersion of millimicron size SiO2 particles in water. The silica particles are non-agglomerated, spherical in shape, negatively charged, and stabilized with a counter ion. The surface of the sol is composed of silanol groups which are partially ionized.

Colloidal silica Wikipedia

Colloidal silicas are most often prepared in a multi-step process where an alkali-silicate solution is partially neutralized, leading to the formation of silica nuclei. The subunits of colloidal silica particles are typically in the range of 1 to 5 nm. Whether or not these subunits are joined together depends on the conditions of polymerization.
