Silica gel is an exceptionally active adsorption material, derived from the reaction of sodium silicate with sulfuric acid, followed by a series of post-treatment processes. It is classified as an amorphous substance with a primary component of silicon dioxide, boasting a purity of over 98%. This inert, non-toxic, and odorless substance is insoluble in water and any solvents, demonstrating stable chemical properties.
