Simple classification of Colloidal Silica

In general, the Colloidal Silica can be classified according to their nature and composition of organic and inorganic Colloidal Silica into two categories. Inorganic silica is a highly active adsorption material, usually with sodium silicate and sulfuric acid reaction, and after aging, acid bulbs and a series of post-processing in the system. Amorphous Colloidal Silica is a material, its chemical formula is mSiO2. nH2O. Insoluble in water and any solvent, non-toxic, odorless, chemically stable, in addition to alkali, hydrofluoric acid does not react with any substance. Various types of Colloidal Silica formation because of their different manufacturing methods and different porous structure.  Colloidal Silicachemical composition and physical structure, determines that it has replaced many other similar hard material characteristics: a high adsorption properties, thermal stability, chemical stability, high mechanical strength Colloidal Silica according to the size of its aperture is divided into : macroporous silica gel, wide poreColloidal Silica , B-type Colloidal Silica,  Colloidal Silicathin silicone hole. Because the different pore structure, so they have their own characteristics of adsorption. Coarse-pored Colloidal Silica in the case of high relative humidity with high adsorption capacity, pore Colloidal Silica  in the case of low relative humidity adsorption capacity than coarse-pored Colloidal Silica, Colloidal Silica as the B-type pore structure between the coarse and fine hole between the amount of adsorption between the thick, between the pore. Macroporous silica is generally used as a catalyst carrier, matting agents, toothpaste abrasives. Therefore, selection should be based on different uses of different varietiesRead more：http://www.chemical-chem.com/Papermaking-chemicals/Colloidal-Silica/
