Colloidal silica are suspensions of fine amorphous, nonporous, and typically spherical silica particles in a liquid phase.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. Initial acidification of a water-glass (sodium silicate) solution yields.


In papermaking colloidal silica is used as a drainage aid. It increases the amount of cationic starch that can be retained in the paper. Cationic starch is added as sizing agent to increase the dry strength of the paper.


High temperature binders

Investment casting – used in moulds

An abrasive – for polishing silicon wafers

Carbonless paper
