Silica gel is an exceptionally active adsorption material, meticulously crafted through the reaction of sodium silicate and sulfuric acid, followed by a series of refined post-treatment processes. This amorphous substance boasts a primary composition of silicon dioxide, with a content exceeding 98%. It is insoluble in water and any solvent, non-toxic, odorless, and exhibits stable chemical properties, making it an invaluable industrial resource.
