Colloidal silica - Wikipedia
Colloidal silicas are suspensions of fine amorphous, nonporous, and typically spherical silica particles in a liquid phase. It may be produced by Stöber process from Tetraethyl orthosilicate (TEOS).
DEFINITION. Colloidal anhydrous silica contains not less than 99.0 per cent and not more than the equivalent of 100.5 per cent of SiO 2, determined on the ignited substance. CHARACTERS.

What is silica - Levasil® colloidal silica - Nouryon
Colloidal silica varies from other types of silica in several significant ways. The most noticeable difference is that it's in liquid form, as opposed to powder. In addition, it has the widest ranging surface area, and its aggregate size can be as small as the actual size of the primary particle.
Colloidal Silica - A Versatile Problem Solver, Product Article
What is Colloidal Silica? In the most general terms colloidal silica is a dispersion of amorphous silicon dioxide (silica) particles in water. These amorphous silica particles are produced by polymerizing silica nuclei from silicate solutions under alkaline conditions to form nanometer sized silica sols with high surface area.
