The appearance of macro-pored micro-spherical silica gel is white transparent or translucent form. Because of its interior structure is a uniform micropore structure, the physical-chemical properties are stable, thermal stability is good, and mechanical strength is high. Its average diameter is 8.0-12.0nm, specific heat is 0.92kJ/kg •°C, and thermal conductivity is 0.167kJ/m•hr •°C
This product is used as the catalyst and catalyst carrier in some important industrial production of melamine, aniline, o-toluidine, vinyl acetate, phthalic anhydride, maleic anhydride, butadiene rubber, acrylonitrile and other products. Also it is widely used in the refined aromatic hydrocarbons removal of petrochemical products. In addition, it can also be used for purification of medicine, selective adsorption separation of organic gas and liquid, and the removal of many harmful elements of the water such as multivalence during the ion-exchange.
