Silica Alumina Gel
- Color : light yellow.
- Chemical molecular formula: SiO2.nAl2O3.xH2O.
It-is chemically stable，flame-resisting，insoluble in any solvent except strong alkali or hydrofluoric acid．Superficial polarity，thermal stability，performance of adsorption and separation are all better than that of fine-pored silica gel．

Use
With higher surface area and drying ability，the absorbent is being widely used in many fields．For its higher compression strength and lower rattle loss,it has longer life and higher performance-value ratio than fine-pored silica gel．
Main application：
1.drying of gas
2.drying of natural gas
3.drying of liquid gas
4.drying of compressed air
