Silica gel is an exceptional adsorption material characterized by its high activity. Typically produced through the reaction of sodium silicate and sulfuric acid, followed by meticulous post-treatment processes, silica gel is an amorphous substance. Composed predominantly of silicon dioxide (over 98% content), it is insoluble in water and any solvents, non-toxic, odorless, and boasts stable chemical properties.
