Colloidal Silica gel is an organic silicone compounds are those containing a Si-C bond, and at least one organic base is directly connected with the silicon atoms of compounds, often used on those by oxygen, sulfur, nitrogen, etc. so that the organic base connected with the silicon atoms of compounds are also used as organic silicon compounds. Among them, the silicon-oxygen bond (-Si-O-Si-) consisting of polysiloxane as the backbone, is the largest number of organic silicon compounds, research the deepest, the most widely used class of about 90% of the total volume of .Colloidal Silica  Is a highly active adsorption material is amorphous material, its chemical formula is mSiO2 · nH2O. Colloidal Silica is insoluble in water and any solvent, non-toxic, odorless, chemically stable, in addition to alkali, hydrofluoric acid does not react with any substance.
