Information About Colloidal Silica

Colloidal silica is used in investment casting manufacturing process.

In order to prepare the shells from  the wax pattern trees, a ceramic slurry is prepared. The main material that gives its specific property to the slurry is colloidal silica. The binding property of the colloidal silica is the key here. Thanks to the binding property of our colloidal silica, an adequate shell around the wax pattern tree occurs and the process can continue further.

The name colloidal silica is given to the product because of the SiO2  (Silica) content. It is in a colloidal form inside the solution. That’s why we call this special silica dispersion as colloidal silica.

Commercial colloidal silica products are available in different concentrations such as 20% - 30% - 40% etc...

30% colloidal silica dispersions are ideal for investment casting. Both the 30% concentrations and the others are not only limited with investment casting applications.

Colloidal silica has a wide variety of application areas such as; investment casting, refractories & castables, paper manufacturing, dental laboratories, beverages, textile, ceramics, paints and coatings.
