1. Colloidal Silica
Basics, Manufacturers,
Technology,
Consultancy, Applications ,
Market Scenario

2. Colloidal silicas
are suspensions of fine amorphous, nonporous, and
typically spherical silica particles in a liquid phase.
The surface of colloidal silica in contact with water
is covered by siloxane bonds and silanol groups.
This makes colloidal silica very hydrophilic and
capable of forming numerous hydrogen bonds.

3. Types:
Alkaline colloidal silica
Acidic colloidal silica
Modified colloidal silica
Ordinary Colloidal Silica

5. What is colloidal silica used for?
It is used as a free-flow agent to assist powder flow,
e.g. in tableting, by reducing the angle of repose of
bulk powder. Surfactant – used for flocculating,
coagulating, dispersing, stabilizing etc. Liquid silicon
dioxide (colloidal silica) is used as a wine and juice
fining agent.
