In general, silica gel can be divided according to their nature and composition of organic silica and inorganic silicone two categories.

Inorganic silica is a highly active adsorption material, usually with sodium silicate and sulfuric acid, and after a series of processing after aging, acid bulbs and prepared. Silicone is non-crystalline material, its chemical formula is mSiO2. nH2O. Insoluble in water and any solvent, non-toxic, odorless, chemically stable, it does not react with any substance except alkali, hydrofluoric acid. Various types of silica because of the way they are formed of different porous structures.

Chemical composition and physical structure of silica, determines that it has many other similar materials difficult to replace characteristics: high adsorption properties, thermal stability, chemical stability, high mechanical strength. Because of its chemical nature so that we use it to do many types of silicone products like silicone seals (What is a silicone ring), silicone seal, etc. fired article.

Silica gel according to the size of the aperture is divided into: large pore silica gel, rough hole silica gel, B-type silica gel, pore silica gel. Due to the different pore structure, adsorption properties so they have their own characteristics. Coarse pore silica at high relative humidity conditions have a higher adsorption capacity, pore silica gel in the case of low relative humidity higher than the coarse pore silica gel adsorption, while the B-type silica gel due to the pore structure between the coarse and fine between the holes, the adsorption amount between the crude, between pores.

Gifts wide pore silica is generally used as a catalyst carrier, matting agents, toothpaste abrasive. Therefore, you should choose different varieties for different purposes.
