Applications

Silica gel is a useful product for column chromatography. It is also used to compare MCM-41 type mesoporous adsorbents. It is exclusively used as a support material for the active titanium(III) centers in Ziegler-Natta catalysts. Silica gel allows a controlled fragmentation resulting in the formation of uniform polymer particles with narrow particle size distribution and high bulk density. It finds it application in drying and cleaning of air and gases, drying of analytical samples, solvents, of synthesis products, optical instruments and devices, protection of Export Consignments from moisture in salty atmosphere, drying and storage of flowers and seeds, desiccant in gas industry, dehydration and purification in oxygen, hydrogen and chlorine, in steel refinery industry and oxygen plant ,it can be used to remove ethane from oxygen.

Notes

Tap density 0.45g/cc, pH (10%. suspension) 4.5
