Silica-gel is a high-activity absorbent, which is the result through chemical reaction between sodium silicate and sulfuric acid and then ageing and sour bathing. Silica-gel is an amorphous substance. Its molecular formula is mSiO2.nH2O. It features a stable chemical property and never reacts with any substance except the alkali and hydrofluoric acid. Because of chemical composition and physical structure of silica-gel, it possesses many advantages as desiccant. For example, high absorption capacity, non-shape changing, etc. It is a non-toxic, odorless and green-environmental material.
