Silica gel, also called silica gel, is an amorphous, porous silicon dioxide (SiO₂) with a high specific surface area of ​​typically 600 – 800 m²/g. It is produced by polycondensation of sodium silicate followed by aging, washing and drying. Due to its adsorption properties, silica gel serves as a desiccant, carrier material or chromatography material in chemical processes. Adsorption occurs physically via van der Waals forces and hydrogen bonds, without structural changes to the material. Silica gel is thermally regenerable and chemically inert to most organic and inorganic compounds. In the chemical industry, it is used for the purification of reaction mixtures, the stabilization of moisture-sensitive substances, and as a support material in catalytic systems. The pore structure and particle size can be specifically adjusted to ensure the required performance for specific applications.
