Silica gel is a highly active adsorption material, amorphous materials, the chemical formula for mSiO2 · nH2O. Insoluble in water and any solvents, non-toxic tasteless, stable chemical properties, in addition to the strong alkali, hydrofluoric acid does not react with any material. Various types of silicone because of the different manufacturing methods and form different microporous structure. Chemical components and physical structure of the silica gel, determines it has many other similar materials difficult to replace features: high adsorption performance, good thermal stability, has high mechanical strength, etc
