    Surface area and pore volume play an integral role in catalyst design, and can be independently controlled during the gel manufacturing process, resulting in various combinations of SA and PV. The size and shape of silica supports have a major effect on controlling the final polymer size and morphology, as well as the productivity of the

    Silica gel - Wikipedia

    Silica gel's high specific surface area (around 800 m 2 /g) allows it to adsorb water readily, making it useful as a desiccant (drying agent). Silica gel is often described as "absorbing" moisture, which may be appropriate when the gel's microscopic structure is ignored, as in silica gel packs or other products.

    Uses of inorganic silica gel and organic silica gel

    Silica gel is a porous material with different particle sizes formed by proper dehydration of silicic acid gel mSiO2·nH2O. It has an open porous structure with a large specific surface (surface area per unit mass) and can adsorb many substances. It is a good desiccant, adsorbent and catalyst carrier. The adsorption of silica gel is mainly

    Silica Aerogel. Silica aerogel is the most common type of aerogel, and the most extensively studied and used. It is silica-based and can be derived from silica gel or by a modified Stober process.The lowest-density silica nanofoam weighs 1,000 g/m 3, which is the evacuated version of the record-aerogel of 1,900 g/m 3. The density of air is 1,200 g/m 3 (at 20 °C and 1 atm).

    Specific Surface Area

    C. Amador, L. Martin de Juan, in Computer Aided Chemical Engineering, 2016. 4.4 Specific Surface Area. The specific surface area of a particle is a function of porosity, pore size distribution, shape, size, and roughness. The role of the specific surface area is critical in the design of a heterogeneous catalyst where typically a domain with high specific surface area (e.g., γ-alumina, silica
