Description

Macroporous silica gel

Characteristics
Macroporous silica gel is a special type of silica gel. Like other silica gels, it is a highly active adsorption material. It is an amorphous substance and its chemical formula is mSiO2·nH2O. Macroporous silica gel is insoluble in water and any solvent, non-toxic, tasteless, chemically stable, and does not react with any substances except strong alkali and hydrofluoric acid. Since the manufacturing method of macroporous silica gel is different from that of other silica gels, different microporous structures are formed. The biggest difference between it and other silica gels is that the pore volume is large, that is, the adsorption capacity is large, and the bulk specific gravity is very light.
