In general, the silica gel according to their nature and composition can be divided into two major categories of organic silica and inorganic silicone. Inorganic silica is a highly active adsorption material, usually sodium silicate and sulfuric acid reaction, and aging, acid bulbs and other post-processing system. The silica gel is amorphous material, chemical formula mSiO2. nH2O. Insoluble in water and any solvent, non-toxic, tasteless, chemically stable, in addition to alkali, hydrofluoric acid does not react with any substance. Various types of silica manufacturing methods and the formation of different porous structure. Chemical composition and physical structure of the silica gel, it is difficult to replace the characteristics of many other similar materials: adsorption properties, good thermal stability, chemical stability, high mechanical strength silicone
Is an organic silicon compound, containing Si-C bond, and at least one organic compounds directly connected to the silicon atom, it is customary often oxygen, sulfur, nitrogen and other organic-based and silicon atoms The compounds are also connected as organic silicon compounds. Among them, the silicon-oxygen bond (-Si-O-Si-) for the skeleton composed of polysiloxane organic silicon compound in the number of most research the deepest, the most widely used class of more than about 90% of the total amount of .
    
Silica gel (Silica, gel Process; Silica,) alias: Silicone rubber is a highly active adsorption material is amorphous material, its chemical formula mSiO2 · nH2O was. Insoluble in water and any solvent, non-toxic, tasteless, chemically stable, in addition to alkali, hydrofluoric acid does not react with any substance. Various types of silica manufacturing methods and the formation of different porous structure. The chemical composition and physical structure of the silica gel, it difficult to replace a number of other similar materials have characteristics: high adsorption properties, thermal stability, chemical stability, high mechanical strength. Silica gel according to the size of its aperture is divided into: macroporous silica gel, wide pore silica gel, B-type silica gel pores of silica gel.
