Colloidal silicas are suspensions of fine amorphous, nonporous, and typically spherical silica particles in a liquid phase.

Detailed description

Applications

·         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

·         Catalysts

·         Moisture Absorbent

·         It increases the bulk & tapped density of powders and granules^{[citation needed]}

·         It is used as a free-flow agent to assist powder flow, e.g. in tabletting, by reducing the angle of repose of bulk powder.

·         Stabilizing and rigidizing refractory ceramic fiber (fiberfrax) blankets

·         Abrasion-resistant coatings

·         Increasing friction - used to coat waxed floors, textile fibers and railway tracks to promote traction

·         Antisoiling – fills micropores to prevent take up of dirt and other particles into textiles

·         Surfactant – used for flocculating, coagulating, dispersing, stabilizing etc.

·         Liquid silicon dioxide (colloidal silica) is used as a wine and juice fining agent.

·         Absorbent

·         Colloidal silica is used in concrete densifiers and polished concrete.

·         In manufacturing Quantum dots, small semi-conductors used in various scientific research settings

·         used as an ingredient in many "Ceramic Coatings"
