Silica gel is form of silicon dioxide, Si02, the material that occurs in nature as sand. The difference between silica gel and sand is that sand is a crystalline, non-porous form, whereas silica gel is non-crystalline and highly porous. Silica gel is an amorphous absorptive substance with stable chemical properties and has a highly complicated porous structure. It is odorless, tasteless, and non-toxic, and offers an excellent capacity for physical and chemical dehumidification.
