Silica gel, an exceptionally active adsorption material, is meticulously crafted through the reaction of sodium silicate with sulfuric acid, followed by advanced post-treatment processes. As an amorphous substance, silica gel's primary component is silicon dioxide, boasting a purity of over 98%. It is water-insoluble, solvent-resistant, non-toxic, odorless, and exhibits remarkably stable chemical properties.
