Silica gel is an exceptionally active adsorption material, typically synthesized through the reaction between sodium silicate and sulfuric acid, followed by comprehensive post-treatment processes. This amorphous substance is primarily composed of silicon dioxide, with purity exceeding 98%. It is insoluble in water and any solvent, non-toxic, odorless, and boasts stable chemical properties.
