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 chemicla composition and physical structure of silica-gel,it possesses many advantages as desiccant.For example,high absorption capacity,non-shape changing,etx.

It is a non-toxic,odorless and green-environmental material.
