Hydrophobic colloidal silica refers to silica nanoparticles that have been chemically modified to repel water. Colloidal silica consists of tiny particles of silicon dioxide suspended in a liquid. These particles are so small that they remain dispersed rather than settling out of solution. Applications Coatings and paints: Hydrophobic colloidal silica can be used as an additive to improve the water resistance and durability of coatings and paints. It helps prevent moisture from penetrating the surface, thereby enhancing the protective properties of the coating. Rheology modifiers: Hydrophobic colloidal silica can be incorporated into various formulations to control rheological properties such as viscosity and thixotropy. This is particularly useful in industries such as cosmetics, adhesives, and printing inks. Catalyst supports: Hydrophobic colloidal silica can serve as a support material for catalysts in chemical reactions. The hydrophobic surface helps prevent unwanted interactions with water, allowing the catalyst to remain active for longer periods. Pharmaceuticals: Hydrophobic colloidal silica may be used in pharmaceutical formulations to improve drug stability, control release rates, and enhance bioavailability.

Silica fume, also known as condensed silica fume or microsilica, is a spherical sub-micron amorphous silicon dioxide used in many applications. Silica fume is a co-product of silicon or ferrosilicon production, consisting of ultrafine (sub-micron), amorphous, non-porous, perfectly spherical silicon dioxide (SiO2) particles, with purity levels of 85 to 99 %. The main effect of these ultra-fine particles is to greatly improve particle packing and produce a highly pozzolanic reaction in concrete and other cementitious bond systems where the silicon dioxide reacts with calcium hydroxide, heightening performance levels and the strength and durability of these materials. Additionally, silica fume, because of its amorphous (non-crystalline) structure and its specific area, provides other useful features to various applications, including improved sintering capabilities and enhanced high temperature performance of refractory castables, resulting in reactions between microsilica and other components of the refractory mix. To summarize, silica fume has two key features which alone or in combination are the basis for its high performance: The nano-sized spherical non-porous particles create an efficient "filler effect" Primary particles have an average diameter of about 0.15 �¼m (150 nanometers) Microsilica is a highly reactive form of silica producing a "chemical effect" Thanks to its amorphous nature and high specific surface area.
