Stabilization of solid dispersions. https://doi.org/10.1039/b921735e, Daz B, Snchez-Espinel C, Arruebo M et al. Finally, fumed silica is commonly referred to as colloidal because the silica powders are made by condensing a silica precursor from a vapour phase. Not only do these silanes provide reactive sites for the grafting of other chemicals, but they provide enhanced stability by physically preventing the formation of siloxane bridges that can result in the formation of aggregates or gel structures. Medium-shear mixers should be used for semisolid products. Publishers note Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations.

Provided the liquid has a refractive index closer to that of the silicon dioxide (i.e., 1.48), generally transparent gels will be obtained. It can be found in nature in crystalline form (as quartz sand), and it is the most abundant component of the earth's crust. Mater Horiz 1:301313.

The following regulatory schedules apply to colloidal silicon dioxide: Several grades of colloidal silicon dioxide are widely available, depending mainly on the method of production, and any subsequent processing changes that the material is subjected to. The interplay between NPs aggregation and degradation has been scarcely explored in the literature when biological fluids are seriously taken into account. Appl Catal A Gen 219:3343. In general, these forces include but are not limited to van der Waals forces, electrostatic forces, liquid bridges, and physical entanglements. Present technology would be very different without the silica used to create the catalysts of our oil refineries, bind the molds for casting super-alloys, form modern glass and ceramics, and polish electronic materials.
