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.
