We are a leading producer of Colloidal Silica ( silica sol) which is used in the production of ceramic fibers & other ceramic products.

We have material with 15% (particle size of 6nm), 30% ( 10-15nm), 40%(10-20nm) in alkali stabilised at pH of 9.5-10.5. We also have acidic colloidal silica with pH of 2-4 .

One of the earliest proposed uses for colloidal silica is in ceramic cements to improve strength. In this type of use colloidal silica acts as an adhesive binder or stiffener at ordinary temperature because it is converted to a solid gel.

In some cases the silica is used for its high chemical activity. Thus when glass powder is coated with colloidal silica it can be molded. When heated, silica dissolves in the glass so that a solid sintered body is obtained. The strengths of colloidal silica as a binder is apparently enhanced by transferring it to an alcohol and producing a mixture with ethyl silicate.

Improved bond strength in ceramic bodies is attained with mixtures of monoaluminum phosphate and colloidal silica when used with finely divided refractory powders of zircon, zirconia, or alumina.
